Electricity is with slow speed and cost. However, anyone can have the latest more sensible choice in data transmission at less the cost and lots of times the speed, the fiber optic.

By using glass or plastic fiber to transmit data, the fiber optic concerns be described as a technology which can switch the position of copper wire. A bundle of glass fibers capable of transmitting messages which can be changed into light waves is what makes the fiber optics. Sharing a variety of technical details within the flowing article, I hope to make you use a better understanding of the subject of fiber optics. The functions will probably be demonstrated by explaining how the technology uses light energy to offer information and data to a selection of sources.

Engineering Science Part of applied science includes data fiber optics and also the engineering behind it is comprised of the science of transmitting data or energy. The basic fundamentals of fiber optics are defined through scientific processes and mathematical equations that fall closely underneath the arena of physics in places you will discover the actual flow with the data may be easily put in observable and replicable systems. So even though a lot of people don't understand what the light is, it could be showed to them through scientific methods.

Fiber optics or optical fibers are often utilized in the concept of imaging optics, sensors, telecommunications, and lighting generally speaking. This can be mainly as a result of data transmission speed cheap it won't require electrical impulses to go the info. It really is resulting in the dependence on electrical power when it comes to data transmission being nearly obsolete since the light transmits energy faster and cleaner than any other know technology.

To grasp the implications on technology by using fiber optics, we must experience how it works when it comes to telecommunications. By conducting signals over distance for communication purposes telecommunications was born. Telecommunications are widespread and there are many devices that assist inside the spread with this communication, like the radio, the fax machine and the television. One of the heavy factors over these mediums is the fiber optics technology.

A telecommunications system's basic fundamentals will be the transmitter, the receiver as well as the transmission medium. A transmitter is definitely an computer that sends an electromagnetic signal using an antenna, essentially taking information and converting it with a signal for transmission which passes it to the transmission medium. A receiver is, of course, the receiving end with the communication channel. The transmission medium may be the material or device that the signal is transmitted.

By serving as an efficient transmitter of data, the fiber optics play an important role in the telecommunications process. Using light energy sent through glass has evolved what sort of world communicates and has revolutionized the process of telecommunications out of this day and into the future.

What Is Bare Fiber Adapter?

Bare fiber adapter is the medium to link the bare fiber to fiber optic equipment. Bare fiber adapter has the bare fiber inside on one side, while the other side is a fiber optic connector that can plug into the equipment. It is also sometimes called bare adaptor, or bare connector.

Bare fiber adapters have brought us a very convenient way to connect unterminated fibers with standard FC, SC, ST, and LC. They can be used in some emergency situation for urgent connection. You can simply strip, cleave, clean and insert the fiber into the adapter which has self-locking mechanism, without the hassle of epoxy and epoxy curing steps. When finished, simply push it out with piano wire. They can be used for thousands of times which is very convenient and cost saving. Bare fiber adapters are perfect for power meter hook-ups and temporary system repairs or wherever a quick connection is required.

Bare Fiber Adapter Applications

1) Temporarily connactorizes bare fiber
2) Testing bare fiber, fiber on the reel, fiber before and after installation
3) Production line of fiber optic devices
4) For fast and temporary fiber optic connections in communication system
5) Temporary connections to OTDR tester, Power Meter, Talk sets, Demo Equipment and Dark Fiber

How To Use Bare Fiber Adapter

1) Strip the outer jacket to about 3 inches
2) Strip the buffer coating leaving about 2 inches of fiber exposed
3) Score and Cleave the fiber, leaving 0.5 inches bare fiber exposed.
4) Once it is cleaved, clean the fiber with Isopropyl alcohol and Kim wipes.
5) Press the clamp button on the bare fiber adapter. Insert the cleaved fiber in the rear of the housing until the glass is flush with the end of the ferrule. Release the clamp button, securing it in place.

Tips: You should not use the adapter with a light source, because physical contact is required at the launching end of a test station. But you can use the adapter with a power meter, just make sure the power meter has a wide-area detector.

In fiber networking installations, workmanship is critical to reach acceptable results because even a small imperfection or microscopic dirt on the face of the fiber can result in significant problems with optical propagation. To help installer avoid these problems, this article offers a hands-on tutorial for fast, safely, and correctly creating fiber optic connections that meet good standards of quality workmanship and ensure optimal coupling efficiency. The following steps for fiber optic cable termination will provide a solid base of information that will have great reference value for both new and experienced field technicians those terminate fiber optic cables often.

1. Insuring Safety
First of all, you should protect yourself during the installation process and leave the installation area in a safe condition for other people beside you. Fundamental safety tools include a dark work surface, such as a black work-mat, and a proper trash receptacle for fiber scraps that is clearly marked as to its contents. Using a piece of black tape to stick your scraps on isn't an acceptable work practice other than just incorrectly flick off the cleaved fiber scraps with fingers which could be harmful to the occupants nearby. Then, use a fiber optic microscope to check a fiber to make sure the other end isn't connected to a power source since the invisible laser light is harmful to the eyes while you may not eve realize you're looking into it until it's too late.

2. Stripping
Once you have got your bulk fiber cable, strip the cable down to the bare fiber using an appropriate fiber stripper. After you have prepared the end of the cable you may begin to mix the epoxy resin and hardener together and load it into a syringe, unless of course you are using pre-loaded epoxy syringes, which are premixed and kept frozen until use. Now, from the syringe you must inject the epoxy directly into the connector ferrule.

3. Inserting
Injet epoxy into the fiber optic connector ferrule and then insert the fiber optic cable so that the cable is seated inside of the connector wall and the bare fiber core sticks out about a half an inch from the front of the ferrule.

4. Crimping
If your cable is jacketed, you will need to use a crimping tool to secure the connector to the jacket and strength member of the cable. Two crimps would be needed at this point.

5. Curing
After that, the next step is to place the connected end into a curing holder to ensure that the end of the fiber is not damaged while curing. Now place the cable and curing holder into a curing oven. To avoid flicking while curing with a conventional oven, situate the connector so that the end is facing down. This positioning will ensure that the epoxy does not come out of the back side of the connector and compromise the strength member of the cable. Then you need to refer to the documentation of your specific epoxy for accurate curing times and temperatures.

6. Cleaving
After you have sufficiently cured the epoxy, you are now ready to move on to the next step, cleaving the excess protruding fiber core. The tool you need is a fiber optic cleaver. Get as close to the ferrule tip as possible while avoiding any sort of twisting motion.

7. Cleaning
Once cleaved, it is important that you properly dispose of the fiber clipping. A regular piece of tape will do just fine at retaining your fiber debris. If you do not properly dispose of all fiber pieces they could easily end up in your skin or even in somebody's eye or respiratory system. A short strand of fiber can cause more damage than you would at first imagine.

8. Polishing
After the excess fiber cleaved and properly disposed of, you can begin the task of polishing the fiber tip to a smooth finish. Using fiber optic polishing tool you can effectively remove any excess epoxy from the ferrule end and buff out any imperfections on the face of the fiber. You can polish the cable tip with the 5-15 micron film, 5 micron aluminum oxide film, 3-6 micron diamond film, 1 micron diamond film, and HX film in order. A smooth fiber surface makes great sense to any light passing through.

9. Cleaning Again
If you have finished with your polished finish, you can move on to the cleaning of the ferrule and fiber tip. Using a lint-free wipe dipped in 99% reagent-grade alcohol, gently wipe the surface area of the ferrule and fiber tip and immediately wipe them dry with another dry lint-free wipe. You may optionally use a can of compressed air to finish the process.

10. Testing
Now the connected cable is complete. The last step is to ensure good standard. First you need to inspect the fiber tip with a 100x to 200x fiber optic microscope. And then test your cable with a fiber optic test equipment for insertion loss and return loss where needed.

In addition, most tools which are used in the steps can be found in a Fiber Termination Kit. Fiber termination technicians should keep such a kit by the side for much more convenience.

Should you be looking for a new ISP, question them about fiber optics on the network. Here are a few avantages that differentiate fiber optics from copper cables.

• Electricity VS. Light

The greatest problem with copper cables is the fact that them all require electricity and in many cases significant amounts of it. You need to think about the outcomes of operating an information network which is heavily reliant on electricity to deliver signals. This is currently when our electrical grids are falling apart and today the cost of energy is merely increasing. However, fiber optics do not rely on electricity to transmit data as it uses light the industry lot cheaper.

• Signal Degradation

One of the leading problems would be that the strength of the electrical signal degrades while on a trip through copper cabling. Same is true for light as it travels through fiber optic cabling, but only a fraction of the loss when compared with copper cables. The more a sign degrades, the greater hardware and sub-stations have to be placed in order to interpret these signals and also to make certain that there's correct transmission from point 1 to suggest 2. More hardware support is required in this case.
Another side effect of degradation in electrical signals is heat and what it does in copper cables along with computers. So, this leaves these networks available to potential failure.

• Upgrades

To be able to support complex signals, more wiring and hardware upgrades are required in the event of traditional copper wiring. Since fiber cabling is not actually affected as a result of heat when compared with copper cables, upgrades are fewer in addition to simpler to perform. Providers with existing wire networks are constantly taking care of ways to boost the performance of existing networks, nevertheless the limits related to sending electricity over copper wiring are really even more than with fiber optic cables that it is wiser to get fiber setups.

Compression algorithms are used to help traditional copper networks, however, this eventually ends up using the users needing to spend more money on more costly modems that are needed to take care of encoding/decoding in addition to compression techniques that are made more complex to keep the copper cables from degrading.

• Effects on Consumers

What does this suggest to consumer - digital television, digital phone services and broadband data plans all using the same fiber optical wire without causing any bottlenecks, congestion, and little data loss. Which means fiber optic networks tend to be more economical in performance, features, and cost. So, this is the way forward for the whole data systems in businesses and houses - fiber optic cable - reliable, low cost plus more features. You may contact FiberStore to get more information on fiber optics prior to going for this as a means of communication for your individual or business needs.

Fiber optic communication industry has been enjoying amazing growth for nearly 20 years, which is driven by both technology advance and market demand. There are some obvious trends inside the growth and development of new technology and market. All-Optical Network and Multi-Terabit Networks could possibly be the first two.

All-Optical Network
All-optical network has become a top topic in fiber optic communication niche for over a decade. Its ultimate goal would be to process all signals in the optical domain with no conversion and controlling to electrical domain in any way.

However, most signal routing, processing and switching occur in the electrical domain up to now. Optical signals must be converted to electrical signal first, and then the electrical signals are processed, routed and switched to their final destination. Following your processing, routing and switching, the electrical signals will be converted to optical signals which can be then transmitted over long distances. This technique is called the O-E-O process.

But this O-E-O process severely limits the rate with the network. Why? Since optical signals can process data faster then today's electronics. The O-E-O process is a bottleneck preventing us from achieving even higher data rates. This bottleneck results in a tremendous interest in all-optical networks where no electronics are required for signal processing, routing and switching.

The advantage of all-optical network is that since all signal processing, routing and switching occurs in optical domain, there is no need to switch the electronics when data rates increase. For instance, current fiber optic transmitters and receivers are equipped for just one single data rate, thus, they ought to be replaced if the data rate increases. But this won't be necessary in a all-optical network.

Admittedly, all-optical network involves be trend of fiber optic communication. However, many obstacles still lie in our approach to make all-optical network a real possibility. Some functions for example reading headers about the optical signals, switching the optical signal on the fly in line with the header content and real-time wavelength switching are just a few of the serious challenges that should be solved before we are able to have a true all-optical network.

Multi-Terabit Networks
DWDM opens the door to multi-terabit transmission. The interest in developing multi-terabit networks is driven through the increasing accessibility to more bandwidth in fiber optic networks.

One terabit network was achieved by using 10Gb/s data rate combined with 100 DWDM channels, while four terabit network may be accomplished by combing 40Gb/s data rate with 100 DWDM channels too. Researchers move their target to even higher bandwidth with 100Gb/s systems. This kind of speed is extremely expensive for make and may just be justified on long-haul systems. However with the price reduction on fiber optic components, devices and systems, more bandwidth is not definately not us.

There are a few other major trends in the fiber optic communication industry too. The most important ones include expansion into mass markets (FTTx), miniaturization, new technology development, cost reductions and even more.

Network Cabling is important for smooth running of business in big organizations where you can find innumerable computers nowadays. Structured cabling is the first step toward all business networks because it provides impeccable connectivity between computers, servers, and lots of other network devices, which permit both data and voice being transmitted all over the world easily.

Most cabling professionals use three basic kinds of cables because both versions is discussed below:

• Co-axial cables: probably the most commonly used cables for establishing a wide range of networks. The co-axial cables include a copper core which is enclosed in foil insulation and is then covered with a layer of braided metal shielding. In areas which have problems with advanced level of interference, Network cabling installation professionals generally use co-axial cables having additional layers of both foil insulation and braided metal shielding.

• Twisted-pair cables: generally split into two sub-categories, namely shielded twisted-pair cables and unshielded twisted pair cables. The cables have core of your pair of insulated copper wires which are wound around one another. As a result of the twisting of the couple of cables, the interference caused by noise or other signals emitted from various gadgets put into their vicinity is minimized.

• Fiber optic cables: undoubtedly given greater preference by network cabling installation professionals, especially in cases when the protection, quality and high speed bandwith are of utmost importance. These cables use high-speed modulated light pulses to transfer data and contain both sending and receiving strands. The main of each of these strands is made from extremely thin glass, which is enclosed within con-centric layers of glass referred to as cladding. Each cable contains one sending strand and receiving strand that are then covered by a protective jacket to make it able to sending in addition to receiving data without having affected its quality.

As technology is advancing daily, the demand for more contemporary and fast types of network cabling is surging, now the fiber cable provides the good result and lots of companies have started utilizing it for installing data cabling infrastructure. It is because there are plenty of advantages of fiber cable, including the ones the following:

• 1. Fiber optic cable can carry signals approximately 50 times longer as compared to the copper wires, because it has very low signal loss rate, and doesn't require a signal repeater to maintain the integrity with the signal over long distances, unlike the copper wires.

• 2. In a cabling system that involves copper wires, you'll be able to detect a sign which is being transmitted through the cable remotely, which eventually presents the loopholes in their security. However, it is not possible regarding fiber optic cable because its dielectric nature can make it impossible to detect the signals remotely.

• 3. Fiber cable has long length, small diameter, and is very light-weight, which eventually makes the installation and upgrade process pretty easy and inexpensive if compared with copper wires.

• 4. This sort of cable provides higher bandwidth and knowledge transfer rate, which eventually cuts down on download some time and increases the network efficiency.

• 5. This cable can be installed in high Electromagnetic Interference (EMI) areas, because it does not have metallic wiring, which eventually makes it completely resistant against EMI.

• 6. This networking cable is very durable and long-lasting, and can be relocated many times.

Since it might be the most important cable in Network Cabling, it's important to discover suitable and cost-effective fiber optic cables to fulfill the business needs. FiberStore supplies all kinds of cables including not just copper cables but also bulk fiber cables for example multimode, single mode, simplex, duplex, outdoor/indoor, ADSS, armored, figure 8 fiber optic cable, and POF cable etc..

What A Business Fiber Optic Network Contains:
The essential philosophy of contemporary LAN wiring may be the idea of structured cabling. The complete networking method is separated into chunks that allow workstation wires to become concentrated. In a typical enterprise LAN system, the fiber optic network contains Telecommunication Rooms, Backbone Wiring, Work Areas and Horizontal Wiring.

• On each floor, there will be a telecommunication room located on top of the other person. These telecommunication rooms hold all network equipment including routers, servers and switches. Telecommunication rooms are linked together with fiber optic cables passing through vertical shafts which are called backbone wiring/cabling or vertical wiring/cabling.

• The backbone fiber optic cables typically run at 10Gbps Ethernet speed to supply enough bandwidth for the whole enterprise.

• Work areas are work stations (PCs) split up into cubicles. These work areas are connected to each floor's telecommunication room with horizontal cabling. These horizontal copper/fiber optic cables typically run at 1Gbps Ethernet speed.

How To Pull The Fiber Optic Cable Through Vertical Shaft:
The backbone cabling was once twisted pair copper cables. The good news is it is normally multimode fibers as well as single mode fibers. There are many tools available to pull the vertical backbone fiber cables. Included in this are Gopher poles, cable caster pulling tools or fish tapes. In most cases you have to put in a pulling eye to guard the fiber cables and connectors while pulling the fiber cables.

How To Terminate A Backbone Vertical Fiber Optic Cable:
The backbone fiber optic cables can be found in without termination (connector). You always have to terminate these fibers with fiber optic connectors such as ST, SC or LC connectors. The termination steps usually are not extremely hard nevertheless it does require some extensive training before you perform a fairly good job.

Fiber optic termination tools

The equipment necessary for fiber terminations are fiber optic cable strippers, Kevlar cutters, fiber cleavers, ST, SC, LC or MTRJ fiber optic connectors, fiber connector hand polishing puck, fiber polishing films and fiber inspection microscope.

Fiber optic cable termination steps

• 1. Strip the fiber: Fiber cables have 3mm jacket, Kevlar strength member and 0.9mm buffer coating. To get at the 0.125mm fiber cladding, you should remove the 3mm jacket having a fiber jacket stripper, then cut the Kevlar fibers having a Kevlar cutter, finally strip the 0.9mm buffer down to 0.125mm cladding having a fiber optic stripper.

• 2. Cleave the fiber: After stripping the fiber as a result of 0.125mm cladding, you insert the fiber into a SC, ST or LC connector, after which inject some fiber optic epoxy in to the connector using a syringe. You will then lay the connector into a hot oven for stopping the fiber epoxy so it can take the fiber tightly. After the curing process, you cleave extra fibers in the connector tip having a fiber optic cleaver.

• 3. Hand polishing the fiber: Within the next step, you place the connector (already with fiber fixed inside) into a hand polishing puck, which serves as a fixture while you polish the end face with the connector to get a good quality mirror like finish. Then you definitely hold the polishing puck and polish the connector over a connector lapping film in a figure 8 shape for 10~15 times. Repeat the hand polishing steps stepping from 12um, 3um to 0.5um lapping films.

• 4. Fiber termination quality inspection: The last step is to inspect the caliber of work. You insert the finished connector right into a fiber optic inspection microscope which zooms to 200 to 400 time level to show you all the scratches and pits which could exist around the connector end face. If everything looks perfect, then you can connect your fiber into the network.

This is only a beginning of building a fiber optic network. Please go to FiberStore for more information. FiberStore is a fiber optic cable supplier who offers a large selection of fiber optic network solutions. You can buy figure of 8 cable and plastic fiber there with high quality!

Q: What is optical fiber connector?
A: Optical fiber connector is used to join optical fibers where a connect/disconnect capability is required. The basic connector unit is a connector assembly. A connector assembly consists of an adapter and two connector plugs. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are generally assembled onto optical fiber in a supplier's manufacturing facility. However, the assembly and polishing operations involved can be performed in the field, for example, to make cross-connect jumpers to size.

Q: Where are optical fiber connectors used?
A: Optical fiber connector is used in telephone company central offices, at installations on customer premises, and in outside plant applications to connect equipment and cables, or to cross-connect cables within a system.

Q: What is the structure of optical fiber connector?
A: Most optical fiber connectors are spring-loaded. The end faces of the fibers in the two connectors are pressed together, resulting in a direct glass to glass or plastic to plastic contact. This avoids a trapped layer of air between two fibers, which would increase connector insertion loss and reflection loss.

Q: Which parameters do optical fiber connectors have?
A: Every fiber connection has two values: Attenuation or insertion loss; Reflection or return loss. Measurements of these parameters are now defined in IEC standard 61753-1. The standard gives five grades for insertion loss from A (best) to D (worst), and M for multimode. The other parameter is return loss, with grades from 1 (best) to 5 (worst).

Q: What types do optical fiber connectors have?
A: There are many types of optical fiber connectors, including FC, LC, SC, ST, D4, MU, MPO, SMA, MTRJ and E2000 etc.. SC and LC connectors are the most common types on the market. The main differences among them are dimensions and methods of mechanical coupling. Generally, organizations will standardize on one kind of connector, depending on what equipment they commonly use. Different connectors are required for multimode, and for single-mode fibers.

In datacom and telecom applications nowadays small connectors (such as LC connector) and multi-fiber connectors (such as MTPconnector) are replacing the traditional connectors (such as SCconnector), mainly to provide a higher number of fibers per unit of rack space. (MTP stands for: Multifiber Termination Push-on connector. It is built around the MT ferrule. Each MTP contains 12 fibers or 6 duplex channels in a connector smaller than most duplex connections in use today. It is designed as a high-performance version of the MPO and will interconnect with MPO connectors. MTP connector is manufactured specifically for a multifiber ribbon cable. The single mode version has a angled ferrule allowing for minimal back reflection, whereas the multimode connector ferrule is commonly flat. MTP connector allows high-density connections between network equipment in telecommunication rooms. It uses a simple push-pull latching mechanism for easy and intuitive insertion and removal. The end of MTP connector may be polished flat or at an 8° angle. It is the same size of a SC connector but since it can accommodate a maximum of 12 fibers, it provides up to 12 times the density, thereby offering savings in circuit card and rack space.

Q: What features does a good optical fiber connector have?
A: Low Insertion Loss; Low Return Loss; Ease of installation; Low cost; Reliability; Low environmental sensitivity; Ease of use.

Q: Where can I buy high cost-effective optical fiber connectors online?
A: FiberStore is the best choice strongly recommended to you.

In contrast to the standard standard copper coaxial cables, fiber optic cable is a new and advanced method utilized in modern telecommunication and data transmission networking applications. Fiber optic cables are made up of transparent glass or plastic fiber which permit light to become guided in one end to the other with minimal loss.

Fiber optic cable has obvious advantages over copper cable with regards to transmission efficiency, capacity, material cost and even environmental friendliness. Listed here are the detailed top seven reasons to opt fiber optic cable versus copper cable.

No.1 - Great Transmission Capacity
In contrast to traditional copper, working frequency of fiber optic is 8-9 orders of magnitude higher, which work a larger carring capacity. Fiber optic cable is capable of carrying much more data than copper. Besides, additionally, it may carry the information for much more distances. For example, a fiber optic can certainly transmit an indication so far as 80 km or more without resorting to amplification.

No.2 - More Transmission Efficiency
In comparison, fiber optic cables can transmit a lot more information, with a greater amount of fidelity. Fiber links offer over one thousand times as much bandwidth over distances more than one hundred times beyond copper. For instance, downloading a 2 GB movie over a typical Fast Ethernet connection (100 Mbps) would take almost 22 minutes. While, downloading the same movie over GPON with fiber cabling, also it would just take about 2 minutes. By providing quicker use of volumes of data which will empower end-users to be easier.

No.3 - Energy Saving And Environmental Friendly
The equipment employed for a GPON fiber optic implementation is usually about 50% more energy-efficient than the traditional networking equipment present in a IDF/Telco closet. This reduction in energy consumption for the IT network does mean there's a huge reduction in the quantity of Greenhouse Gas emitted in to the atmosphere.

No.4 - Free of Interference
Unlike electrical cables which conduct with electricity, fiber optic cables are glass-based carring light signals. This eliminates the requirement for grounding and means they are immune to any type of electrical interference - even lightning. Taking the benefits of potential to deal with interference and atmospheric conditions, outdoor fiber optic cables may be used outdoors as well as closeness to electrical cables without concern.

No.5 - More Data Secured
Aside from interference-free, class fibers may also work well in roughing conditions. We know, copper cabling is sensitive to water and chemicals, class fiber cabling runs nearly no risk of being damaged by harsher elements. Fiber Optic cables can certainly endure living environment that coaxial cable just cannot, for example being buried with soil, or in close proximity to chemicals. Besides, as it is also far more difficult to tap, fiber cabling would offers extra security for the data being transmitted.

No.6 - Easy Handling And Installation
Fiber optic cables are much lighter and smaller as compared to copper-based cables, which make it quicker to handle and require less time and effort to set up. Additionally, the carriers would never get shocked when the fiber optic cables are break as the electrical coaxial cables do. Since fiber cabling transmits light and not electricity, the folks handling it run no risk of injury from fire, sparking or electrocution.

No.7 - Cost Effective
Using the growth and development of fiber optic technology, fiber optic cable is no longer always regarded as too fragile or expensive for the deployed for general applications, by contract, it has gets to be more simpler to work with and install. With various cable metal material price rising around the present market, while optic fiber has declined and the manufacturing processes are also improving, that has created an essential prerequisite for the quick development of optical communication.

FiberStore, the best fiber optic cable supplier from China, can provide all kinds of fiber optic cables including glass optical fiber and plastic optical fiber. Whether single-mode and multimode(OM3, OM4), or simplex and duplex, outdoor and indoor cables are all available.

Optical fiber is a flexible and transparent fiber made of glass or plastic that transmits light between the two ends of the fiber. Generally used in fiber optic communications, which permit transmissions over longer distances and at higher bandwidths, optical fibers provide better services compared to other forms of communication.

Nowadays, fiber optic cables are gaining in popularity, rapidly replacing traditional copper transmission cables. Instead of transmitting signals with electrical impulses like copper lines, fiber optic cables use light pulses that propagate through small strands of silica glass. To send data, a light source such as an LED or a laser is placed at one end of the cable. Copper wires are delicate and difficult to maintain, while fiber optic cables are durable, have stronger tension and are cheaper. Fiber cabling is not only required by large business corporations but also at home for smoother communication.

The most commonly used fiber optic cables are single mode, multimode and plastic optical fiber (POF). Multimode fibers are used for short-distance communication links and for applications where high power must be transmitted, while single-mode fibers are used for most communication links over one kilometer. Both single-mode and multimode fiber optic cables are made out of glass.

In contrast with glass fiber, plastic fibers use harmless green or red light that is easily visible to the eye. Plastic fibers can be safely installed in a home without risk to inquisitive children. A second advantage is their toughness. Plastic fibers are much thicker than glass fibers, a millimeter or more, and can be handled without special tools or techniques. You need not be trained to handle and install it. You just cut it with scissors, plug it in and it works.

POF is an optical fiber which is made out of plastic. Similar to traditional glass fiber, POF transmits light through the core of the fiber. But the core size of POF is in some cases 100 times larger than glass fiber. As fiber technology continues to become more flexible and less expensive, Plastic fibers are generally more cost effective than glass fiber optic cables and are ideal for applications that require continuous flexing of the fiber. POF cables are constructed of a single acrylic monofilament and are most efficient when used with visible red status indicator light sources. A wide range of fiber optic tips are available. POF has been called the consumer optical fiber because the fiber and associated optical links, connectors, and installation are all inexpensive. The per fluorinated polymer fibers are commonly used for much higher-speed applications such as data center wiring and building LAN wiring.

As a topping fiber optic cable supplier, FiberStore offers high-quality products at an affordable price. Except the traditional single-mode and multimode glass fibers, we also supply figure of 8 cable and POF cable.

Materials For Optical Fibers
There's two major kinds of optical fibers: plastic optical fiber (POF) and glass optical fiber.

POF fiber is usually designed for lighting or decoration such as fiber optic christmas trees. It is also used on short range communication applications for example on vehicles and ships. Because of plastic optical fiber's high attenuation, they've limited information carrying bandwidth.

Whenever we talk about fiber optic networks and fiber optic telecommunications, we actually mean glass optical fibers. Glass optical fibers are mostly made from fused silica (90% a minimum of). Other glass materials such as fluorozirconate and fluoroaluminate are also utilized in some specialty fibers.

Glass Optical Fiber Manufacturing Process
Before we start talking how you can manufacture glass optical fibers, let's first check out its cross-section structure. Optical fiber cross section is really a circular structure composed of three layers inside out.

• A. The inner layer is called the main. This layer guides the sunshine and prevent light from escaping out with a phenomenon called total internal reflection. The core's diameter is 9um for single mode fibers and 50um or 62.5um for multimode fibers.

• B. The center layer is called the cladding. It has 1% lower refractive index than the core material. This difference plays part in total internal reflection phenomenon. The cladding's diameter is usually 125um.

• C. The outer layer is called the coating. It is actually epoxy cured by ultraviolet light. This layer provides mechanical protection for the fiber and helps make the fiber flexible to handle. Without it coating layer, the fiber will be very fragile and simple to interrupt.

Due to optical fiber's extreme tiny size, it's not practical to produce it in one step. Three steps are required once we explain below.

1. Preparing The Fiber Preform
Standard optical fibers are created beginning with constructing a large-diameter preform, with a carefully controlled refractive index profile. Only several countries including US be capable of make large volume, high quality fiber preforms. The process to create glass preform is known as MOCVD (modified chemical vapor deposition). In MCVD, a 40cm long hollow quartz tube is fixed horizontally and rotated slowly on the special lathe. Oxygen is bubbled through solutions of silicon chloride (SiCl4), germanium chloride (GeCl4) and/or other chemicals. This precisely mixed gas is then injected in to the hollow tube. Because the lathe turns, a hydrogen burner torch is moved up and down the outside of the tube. The gases are heated by the torch as much as 1900 kelvins. This extreme heat causes two chemical reactions to happen.

• A. The silicon and germanium interact with oxygen, forming silicon dioxide (SiO2) and germanium dioxide (GeO2).

• B. The silicon dioxide and germanium dioxide deposit on the inside of the tube and fuse together to form glass.

The hydrogen burner will be traversed up and down the length of the tube to deposit the fabric evenly. After the torch has reached no more the tube, it is then brought back to the beginning of the tube and the deposited particles are then melted to create a solid layer. This method is repeated until an adequate amount of material has been deposited.

2. Drawing Fibers On The Drawing Tower
The preform will be mounted to the peak of the vertical fiber drawing tower. The preforms is first lowered into a 2000 degrees Celsius furnace. Its tip gets melted until a molten glob falls down by gravity. The glob cools and forms a thread because it drops down. This starting strand will be pulled via a number of buffer coating cups and UV light curing ovens, finally onto an electric motor controlled cylindrical fiber spool. The motor slowly draws the fiber from the heated preform. The formed fiber diameter is strictly controlled by a laser micrometer. The running speed of the fiber drawing motor is about 15 meters/second. Up to 20km of continuous fibers could be wound onto a single spool.

3. Testing Finished Optical Fibers
Telecommunication applications require very high quality glass optical fibers. The fiber's mechanical and optical properties will be checked.

Mechanical Properties:

• A. Tensile strength: Fiber must withstand 100,000 (lb/square inch) tension

• B. Fiber geometry: Checks fiber's core, cladding and coating sizes

Optical Properties:

• A. Refractive index profile: Probably the most critical optical spec for fiber's information carrying bandwidth

• B. Attenuation: Very crucial for long distance fiber optic links

• C. Chromatic dispersion: Becomes more and more critical in high-speed fiber optic telecommunication applications

After the testing are finished, the optical fiber can be made as fiber optic cable for sale. Whatever kinds of common cables, including single-mode and multimode, or other special ones like figure of 8 cable, are made of glass optical fiber. FiberStore supplies bulk fiber cables which are all strictly manufactured.

Fiber optic cable has become a standard component in a majority of cable infrastructures. This is because it can transport signals across large distances quickly and is immune to electromagnetic interference and radiofrequency interference. How to choose the right fiber optic cable? Here are some factors to consider before you buy optical cable.

1) The first is the type of fiber mode required. There are two options which are single-mode and multimode. Single-mode fiber optic cable is primarily used for extreme bandwidth applications as well as when data must be passed over extremely long distances. Multimode fiber allows each signal to travel in multiple pathways simultaneously. There are several different types of multimode fiber optic cables which offer different levels of bandwidth capacity.

2) The second is how much fiber optic cable is needed. In most cases, it is purchased by reel. The length of cable on each reel can vary from one manufacturer to the next and can exceed 16,000 feet per reel.

3) The third is the fiber cable jackets. The most common jackets available include indoor only, outdoor only, indoor/outdoor, and tactical. Some manufacturers offer customizable colors, while others use a standardized jacket color.

4) The internal construction of the fiber optic cable is important to consider as well. Apart from the plastic optical fiber, there are four basic types of internal construction of common glass optical fiber; however each type can vary based upon customer specifications.

• The first type is referred to as distribution or tight pack. All of the fibers are under a single jacket.
• The second is a breakout or fanout design. Each buffered fiber has its own individual jacket under a larger, overall jacket. This makes it tougher and more durable.
• Another popular internal construction is known as zip cord or assembly. This technique uses one or two buffered fibers in individual jackets. As a general rule, single fiber cable is only recommended for patching. There are also some special ones such as figure 8 fiber optic cable.
• The final option is loose tube. It utilizes non-buffered fibers through a tube filled with a water repellent gel compound.

5) The final factor to consider is the level of flame resistance. Most fiber optic cable has three different grades to choose from. They are general, high, and special. The level of flame resistance is normally determined by testing flame propagation and smoke density values.

While there are a variety of additional factors which need to be considered on a case-by-case basis, the five primary factors remain unchanged. They include the types of fiber mode, fiber cable jackets, internal construction, and level of flame resistance. By focusing on these five factors, it ensures that businesses can quickly identify the right fiber optic cable for their needs.
