I have tried to know the Punch down tool and get imformation from Wikipedia. It’s not interesting but necessary to our works in fiber optic areas. A punch down tool is also called a punchdown tool or a krone tool. You can also call it this name krone punch down tool if you like. It’s a small hand tool used by telecommunication and network technicians for inserting wire into insulation-displacement connectors on punch down blocks, patch panels, keystone modules, and surface mount boxes.

When krone punch down tool compare prices, we FiberStore supply the krone punch down Tool with competitive price which is the cheapest in thee peers. For more information, please contact our sales representative right now from “krone punch down tool buy“. Save your time & money for your business or project in Fiberstore!

Now let me introduce it to you. Most punch down tools are of the impact type, consisting of a handle, an internal spring mechanism, and a removable slotted blade. To use the punch down tool, a wire is pre-positioned into a slotted post, and then the punch down tool is pressed down on top of the wire, over the post. Once the required pressure is reached, the internal spring is triggered, and the blade pushes the wire into the slot, cutting the insulation, and securing the wire. For light-duty use, there are also less expensive punch down tools with fixed blades and no impact mechanism. To accommodate different connector types, 66, 110, BIX and krone require different blades. Removable blades for 66 or 110 are often double-ended, with one end that only inserts the wire for daisy-chain wiring from post to post, and another end that inserts wire and trims the excess length for termination at a post. The trimming blade cutting edge works against the plastic insulating post. Krone blades require a separate scissor-like mechanism for trimming the wire.

To know more about the punch down tool, I select one of our products to explain in details.

What’s WDM? It’s short for Division Multiplexing Wavelength technology. A WDM system uses a multiplexer at the transmitter to join the signals together, and a demultiplexer at the receiver to split them apart. It contains DWDM and CWDM.

DWDM is short for Dense Wavelength Division Multiplexing, an optical technology used to increase bandwidth over existing fiber optic backbones.DWDM transmission technique through optical fiber using the C band (1550 nm). That is a multiplexing method very similar to the frequency division multiplexing is used in electromagnetic transmission means. Several carrier signals (optical) are transmitted by a single optical fiber using different wavelengths of laser beam each. Each optical carrier is an optical channel that can be treated independently of other channels that share the medium (fiber optic) and contain different types of traffic. In this way can multiply the effective bandwidth of the optical fiber, so as to provide bidirectional communications. This is a very attractive transmission technique for telecom operators by allowing them to increase capacity without additional wiring or trenching. To transmit using DWDM is needed from complementary devices: a transmitter side muxer y demuxer at a receiver side it.

DWDM modules inlcude DWDM demux(mux) module and DWDM OADM module. As for DWDM demux(mux), the common configuration is 2CH, 4CH, 8CH, 16 CH, 32CH, 40CH channels. They are available in the form of Plastic ABS module cassette, 19″ rack mountable box or standard LGX box. And no matter what kind of connectors, like FC, ST, SC, LC etc, all are available on our website, and we also can mix connector on one device. A key advantage to DWDM is that it’s protocol- and bit-rate-independent. DWDM-based networks can transmit data in IP, ATM, SONET /SDH, and Ethernet, and handle bit rates between 100 Mb/s and 2.5 Gb/s. Therefore, DWDM-based networks can carry different types of traffic at different speeds over an optical channel.

CWDM is short for Coarse Wavelength Division Multiplexing. Originally, the term “coarse wavelength division multiplexing” was fairly generic, and meant a number of different things. In general, these things shared the fact that the choice of channel spacings and frequency stability was such that erbium doped fiber amplifiers could not be utilized. Prior to the relatively recent ITU standardization of the term, one common meaning for coarse WDM meant two (or possibly more) signals multiplexed onto a single fiber, where one signal was in the 1550 nm band, and the other in the 1310 nm band.

CWDM modules include CWDM mux/demux module and CWDM OADM module. The common configuration of CWDM mux/demux module is 2CH, 4CH, 8CH, 16CH, 18CH CWDM mux/demux module. 3 Single fiber or dual fiber connection for CWDM Mux/demux are available. Accordingly, they have two important characteristics inherent in systems employing CWDM optical components which allow easier and therefore also cheaper than in DWDM systems. CWDM is very simple in terms of network design, implementation, and operation. CWDM works with few parameters that need optimization by the user, while DWDM systems require complex calculations of balance of power per channel, which is further complicated when channels are added and removed or when it is used in DWDM networks ring, especially when systems incorporate optical amplifiers.

Category 6 cable, commonly referred to as Cat 6, is a cable standard for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards.Compared with Cat 5 and Cat 5e, Cat 6 features more stringent specifications for crosstalk and system noise.The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet) and 10GBASE-T (10-Gigabit Ethernet).Whereas Category 6 cable has a reduced maximum length when used for 10GBASE-T; Category 6a cable, or Augmented Category 6, is characterized to 500 MHz and has improved alien crosstalk characteristics, allowing 10GBASE-T to be run for the same distance as previous protocols.

Like most earlier twisted-pair cable, Category 6 cable contains four twisted wire pairs. Attenuation, near end crosstalk (NEXT), and PSNEXT (power sum NEXT) in Cat 6 cable and connectors are all significantly lower than Cat 5 or Cat 5e, which uses 24 AWG wire.The increase in performance with Cat 6 comes mainly from increased (22 AWG) wire size.The heavier wire in some Cat 6 cables makes them too thick to attach to standard 8P8C connectors without a special modular piece, resulting in a technically out-of-compliance assembly.Because the conductor sizes are generally the same, Cat 6 jacks may also be used with Cat 5e cable.Category 6 cable can be identified by the printing on the side of the cable sheath.Cat6 patch cables are normally terminated in 8P8C modular connectors. If Cat 6 rated patch cables, jacks, and connectors are not used with Cat 6 wiring, overall performance is degraded to that of the cable or connector.Connectors use either T568A or T568B pin assignments; although performance is comparable provided both ends of a cable are the same, T568B is a deprecated standard in the US and no longer supported by TIA. In Europe, however, EIA supports T568B only.

FiberStore.COM supply high quality low cost Cat5e/Cat6 Ethernet network Patch Cables, Cat5e and Cat6 UTP FTP Cable. Our Cat5e/Cat6 FTP UTP Patch Cables are suitable for all your data and networking requirements.

Optial splitter is used to split the fiber optic light into several parts at a certain ratio. Fiber optic splitters are important passive components used in FTTX networks. But two kinds of fiber optic splitters/couplers are popular used, one is the traditional fused type optical splitter (FBT coupler), which features competitive prices; the other is PLC splitter, which is compact size and suit for density applications. Both of them have its advantages to suit for different requirement.
Fiber optic splitters can be terminated with different kinds of connectors, the main package could be box type or stainless tube type, one is usually used with 2mm or 3mm outer diameter cable, the other is usually used with 0.9mm outer diameter cables.

In Fiber to the Home (FTTH) networks, Gigabit Ethernet PON splitters play an important role by allowing a single PON network interface to be shared among many subscribers. There are two basic technologies for building passive network optical splitters: Fused Biconical Taper (FBT) and Planar Lightwave Circuit (PLC). Fused Biconical Taper is the older technology and generally introduces more loss than the newer PLC splitters, though both PLC and FBT splitters are used in PON networks. Splitters are installed in each optical network between the PON Optical Line Termination (OLT) and the Optical Network Unit(ONU) that the OLT serves. Networks implementing BPON, GPON, EPON, 10G EPON, and 10G GPON technologies all use these simple optical splitters. In place of an optical splitter, a WDM PON network will use an Arrayed WaveGuide (AWG).

Dense Wavelength Division Multiplexing(DWDM) refers to a fiber optic data transmission technology, which parallel transmission using the wavelength of the laser in accordance with the bit or the string line transmission mode in the optical fiber transmission data.

DWDM has three characteristics:(1)Internet diversified services. DWDM and independent of the transmission rate and the Statute that provide and service the form completely unrelated to the transmission network, for example: a transfer rate and the Statute completely transparent DWDM networks and ATM, IP, SDH signal mediated pick provide diversified services network.(2)Reduce costs, improve service quality. Compared to traditional signal assignment or scheduling in optical layer in the layer bandwidth scheduling more simple and efficient, you can reduce expenses. Another network fiber cut or optical signal failure in the optical layer the signal protection switch or network routing reply actions relative to the traditional electric layer reply actions switching time is shorter, so that the network availability increase and improve service quality. (3)Enhance the transmission distance and increase the network capacity. The biggest problem is that on the high speed of STM-64 TDM transmission fiber dispersion serious for the transmission of the light signal will produce deterioration effect, therefore, if you do not use the electronic reproduction or other compensation techniques, theoretically STM-64 signal in G.652 fiber transmission is about 60 km. Terms of the eight-wavelength DWDM technology transfer, each wavelength 2.5Gb / s of the signal, its transmission capacity for 20 Gb / s, the transmission distance of up to 600 km without electronic regenerator, and the need to light amplifier.

Coarse Wavelength Division Multiplexing(CWDM) and DWDM have certain similarities, the main difference is there are three points: (1) CWDM the Lightwave channel spacing wide light wavelength less than DWDM multiplexed on the same fiber. (2) CWDM optical modulation using a non-cooled laser with electronic tuner; DWDM is used in cooling the laser, with the temperature tuning. Because the temperature in a very wide sections of the optical wavelength is very unevenly distributed, therefore temperature tuned to achieve them is very difficult, the cost is also high. CWDM avoid this difficulty, thus greatly reducing the cost, the current the CWDM system cost general only 30% of DWDM. (3) CWDM system power consumption and physical size smaller than DWDM systems.

FiberStore supply 2 types of WDM Equipment, which is DWDM module and CWDM module devices. DWDM modules inlcude DWDM mux/demux module and DWDM OADM module.

Fiber optics is a type of technology that uses an optical signal instead of an electrical one to send data from one place to another. The cable is made either of glass or plastic coated in plastic, instead of the copper wire that was commonly used in the past. A fiber-optic splitter is a device that takes a single fiber optics signal and divides it into multiple signals.

The use of fiber optic technology has become increasingly popular for several reasons. Fiberoptic cables are much less sensitive to electrical interference, making them more reliable than older types of cabling. They are also able to carry very large amounts of data in comparison with what older systems can handle. This makes them much more efficient, despite the facts that there are some drawbacks to the system. The cables require a thicker covering to protect the optical cables and they also need to have repeaters installed to boost the signal strength in order for the system to work, two hindrances to the use of this technology.

Despite the limitations, fiber optics technology is in use for both home and commercial applications. Phone companies in many nations use fiber optics cables to carry long distance telephone transmissions. Due to the cost, however, they are not commonly used for local calling. The system requires both boosters and splitters in order to send the signals to the appropriate location, adding to the cost and complexity. One frequent use of a fiber optic splitter in the home is to split a television signal so that it goes to more than one TV.

Optical splitter is used to split the fiber optic light into several parts at a certain ratio. Fiber optic splitters are important passive components used in FTTX networks. But two kinds of fiber optic splitters/couplers are popular used, one is the traditional fused type optical splitter (FBT coupler), which features competitive prices; the other is PLC splitter, which is compact size and suit for density applications. Both of them have its advantages to suit for different requirement.Fiber optic splitters can be terminated with different kinds of connectors, the main package could be box type or stainless tube type, one is usually used with 2mm or 3mm outer diameter cable, the other is usually used with 0.9mm outer diameter cables

The most common type of fiber-optic splitter splits the output evenly, with half the signal going to one leg of the output and half going to the other. It is possible to get splitters that use a different split ratio, putting a larger amount of the signal to one side of the splitter than the other. Splitters are identified with a number that represents the signal division, such as 50/50 if the split is even, or 80/20 if 80% of the signal goes to one side and only 20% to the other.

Some types of the fiber-optic splitter are actually able to work in either direction. This means that if the device is installed in one way, it acts as a splitter and divides the incoming signal into two parts, sending out two separate outputs. If it is installed in reverse, it acts as a coupler, taking two incoming signals and combing them into a single output. Not every fiber-optic splitter can be used this way, but those that can are labeled as reversible or as coupler/splitters.
There are many fiber optic devices china, Fiberstore provides all kinds of the devices, if you need these, please contact us.

Introduction

Dense wavelength division multiplexing (DWDM)transmission systems, which have conventionally been adopted in long-haul backbone networks, are now being adopted in metropolitan area networks along with the recent rapid spread of multimedia services as typified by the Internet. In the applications for metropolitan area networks, the small form-factor pluggable (SFP) and other types of small optical transceivers are generally mounted in high density. Therefore, the development of DWDM optical transceivers in SFP package had been awaited.
Utilizing the accumulated technologies in SFP designing and wavelength control, the authors have successfully developed a 2.5Gbps optical transceiver for DWDM applications in the SFP platform (DWDM-SFP)by developing a compact coaxial transmitter optical subassembly (TOSA) with an integrated Peltier device.

Development of compact coaxial TOSA with integrated Peltier device
The external view of the newly developed coaxial TOSA with an integrated Peltier device and its pin assignments are shown in Fig. 1 and Fig. 2, respectively. A DFB laser diode (LD), a monitor photo diode (PD), a newly developed Peltier device for controlling the LD temperature and a thermistor for detecting the LD temperature are built into an 8-pin package. An isolator and a fiber receptacle are attached on it. By downsizing these internal parts and minimizing the heat load to reduce the power consumption, the authors realized a cooled coaxial TOSA that is 5.6 mm in diameter and 12.7 mm long, which is one-eighth the size of conventional cooled butterfly-type modules.
Figure 3 shows the case temperature dependence of he module’s power consumption. In this evaluation, he temperature and the current of the LD are set to 40 deg. C and 35 mA, respectively. As a result, the power consumption is successfully suppressed to 230 mW or lower, which is eight times smaller than the conventional butterfly-type module. This makes it easy to realize a DWDM-SFP having low power consumption and simple heat radiation structure.

Development of package
SFP is a pluggable optical transceiver of the size of little finger that is inserted into the open port of communication equipment as shown in Fig. 4. The outline dimensions and other important dimensional specifications of the SFP, such as the receptacle part that the optical connector is inserted into and the edge connector mating with the electrical connector of communication equipment, are standardized by a multi source agreement (MSA). The objective of the development was to create a package that meets not only MSA but also the following structure requirements at a low cost;1) the high-density packaging structure, 2) the efficient heat-radiating structure, and 3) the electromagnetic interference (EMI) shield structure. The solutions for satisfying these requirements are described below.
To realize the high-density packaging structure, the authors optimized the three-dimensional arrangement of the internal structure including the outline of the printed circuit board (PCB) and the electronic components on it.The maximum operating case temperatures of DWDM-SFP and TOSA are 70 and 75 deg. C, respectively. Therefore, it is necessary to keep the temperature difference between SFP and TOSA within 5 deg. C. The part number 1 and number 2 in Fig. 5 which take on the function of radiating heat, are made of copper alloy and their thermal conductivities are 350 and 300 W/mK, respectively. The part number 1 has the function of transporting heat from the transceiver IC
and other components mounted on the PCB to the rear of the SFP. The heat from TOSA and receiver optical sub-assembly (ROSA) is transported by the thermal sheets at the upper and bottom sides of the package. Figure 6 is a conceptual diagram showing these three heat conducting paths, and Fig. 7 shows the result of the thermal simulation. In Fig. 7, the temperature of the area“a” is low enough compared to that of the other areas, which indicates that TOSA is well separated thermally from other heat sources. Figure 8 is the measurement result of the case temperature difference between TOSA and SFP. It shows that the temperature difference is below 5 deg. C at any condition.3-3 EMI shield structure The typical method for creating an EMI shield structure is to give metal plating to the receptacle part. Because metal plating is costly, the authors developed a new structure for EMI shielding by three-dimensionally assembling the internal sheet metal parts instead of conducting the plating process to the receptacle part. Figure 9 shows the result of the EMI measurement of 16 pieces of DWDM-SFP. The Federal Communications Commission (FCC) specifies that the electromagnetic radiation is to be strictly limited to below 54 dBuV/m.

There are also have some development in circuit board and Wavelength control technique, here we just not describe in details.

Conclusion
The authors have successfully developed a SFP-sized 2.5Gbps optical transceiver for DWDM applications. Miniaturization and low power consumption (1 W) are achieved by developing the following approaches; a compact coaxial TOSA with an integrated Peltier device, an optimized heat-radiation structure, and a high-density mounting board with the newly developed transceiver IC. In addition, the optimized TOSA design and precise wavelength control by CPU have allowed the transceiver to have a good wavelength stability, which sufficiently meets the 100 GHz grid spacing with only the temperature control of direct modulated LD. Moreover, an excellent characteristic was achieved in long-haul transmission. The authors are planning to develop the DWDM-SFP having higher added values, such as further low power consumption and RoHS compliance, in future. If you want to know more professional knowledge about the SFP or DWDM/CWDM/OADM, please contact fiberstore. Here we will provide products such as CWDM/DWDM/modules, andCWDM OADM and DWDM OADM modules (such as DWDM 1 channel OADM).

The colored wire loom can be also described as colored split wire loom or know as colored convoluted tubing. It is a flexible polyurethane corrugated tube with a split down the side where you can insert your cable bundle, it is one of the most popular cable management products that can hold groups of wires together. Usually, the colored wire loom can be used in a wide range of applications, it can be used as cable protector and cable organizer at the same time, which means it can be used as your wiring convention and also protecting your wires and cables against abrasion and crushing. In speaking of the functions, the cable organizer is very efficient if there’s an instance where you have to add another wire subsequently, you can just easily slip it into the split wire loom without having to remove the whole cable or wire bundles. The colored wire loom that provided on FiberStore.com is a cinch to install, it is extremely durable and UV stable, the slit down the length of the tubing allows easy wire insertion yet basically remains closed during using and the corrugated design adds crush strength the loom as well as flexibility.

Then let's focus on the Optical time-domain reflectometer. The OTDR is a classic optoelectronic instrument used to characterize an optical fiber. In its testing work, it injects a series of optical pulses into the fiber, it could give you an overview of the whole system you test. It extracts, from the same end of the fiber, light that is scattered (Rayleigh backscatter) or reflected back from points along the fiber (This is equivalent to the way that an electronic time-domain reflectometer measures reflections caused by changes in the impedance of the cable under test). An OTDR may be used for estimating the fiber optic cable length and fiber optic cable overall attenuation, which including splice and mated-connector losses, and the OTDR can be also be used to locate faults, such as breaks, and to measure optical return loss. There are many types of OTDRs that designed for single mode troubleshooting, multi mode troubleshooting, both single mode & multi mode troubleshooting on the FiberStore.com website now, and the species nearly cover all the famous manufacturer of OTDR in the world. And for all the OTDR tester sale, we FiberStore.com provide one year warranty for each domestic and foreign brand product. Welcome to contact the FiberStore in case you have any problems or special requirement. We will try our best to provide you the best service.

Multiplexing is the process of transmitting several different signals or information streams via a single carrier. The transmission of all these signals or streams takes place simultaneously by combining the several signals into one common signal that will efficiently moves through the carrier bandwidth. Once the signal reaches the destination point for one of the transmissions, that integrated signal re-assimilates into its original form and is received.

The exact configuration of the process depends a great deal on the mode or type of transmission. When dealing with an analog transmission, the signals are multiplexed using a process that is known as frequency-based multiplexing. This form, usually referred to as FDM, uses a process of dividing the bandwidth into a series of subchannels that will accommodate the transmissions and more or less allow them to flow forward in a parallel fashion.

A second common type is time-division multiplexing, or TDM. With TDM, the various signals or transmissions are carried over a common channel in much the same way as with FDM. The main difference is that the time-division approach allows for the signals to be transmitted in a series of alternating time slots. These alternating slots are still carried within a common channel, and still fit neatly into the available bandwidth.

Multiplexing is one of the common tools used today in just about every form of communications. A wide range of telephony services, including online applications, are able to function with such a high degree of efficiency because of the current technological advances this process has made possible. Optical networks also rely heavily on multiplexing to carry voice and video transmissions along concurrent but separate wavelengths from a point of origin to various points of determination. With an increasing range of communication functions taking place across the Internet, it has become an effective tool that aids in everything from videoconferences and web conferences to large data transmissions to even making a simple point-to-point telephone call.

There are many kinds of the multiplexing, such as video multiplexing, data multiplexing, video/data multiplexing, frequency division multiplexing, voice/data multiplexing, optical multiplexing, etc. Everyone can choose what is suitable for him. What’s more, there are also many other fiber products that are very useful, like fiber cleaver(CT 30A fiber cleaver is recommended), fiber optic transceiver, fiber media converter, fiber patch cable, fiber optic tester(OTDR, optic power meter, PON power meter ), fiber cabling, CWDM and DWDM and so on.
