The difference between the cable and the optical cable

Cable: when the unit will sound signal into electrical signal through the line after the transfer to the switch, and then by the switch by lines will signal directly to the other telephone answering a call, the process of transmission lines is cable. The inside of the cable is mainly copper core wire. The diameter of the core wire with 0.32mm, 0.4mm and 0.5mm points, the greater the diameter of communication ability is stronger; and according to the core line number, are: 5, 10, 20 of of of, 50, 100, 200 of of of and so on, here refers to the maximum number of users log cable hold and press; packing, this I do not know. Cable: the volume, weight, communication ability, can only be used for short distance communication. Cable: when the unit will sound signal into electrical signal through the line after the transfer to the switch, and then by the switch will this electrical signal is transmitted to the photoelectric conversion device (converts electrical signals into light signals) to another photoelectric conversion device by lines (convert optical signals into electrical signals), then to switching equipment, to the other telephone answering. In between the two photoelectric conversion device is the optical cable line. With that number it only core line of the points, the core line number: 4, 6, 8, 12 and so on. Cable: its volume, small weight, low cost, large communication capacity, the advantages of good communication. Because of many factors, it is only used for long distance and from point to point (i.e. two switching) communication between. The difference between them is: inside the voice patch panel copper core wires; cables inside the glass fiber. Optical fiber communication cable is a certain amount in a certain way to form the cable core, a sheath of outsourcing, and some also covered the outer protective layer, with a line of communication to achieve the optical signal transmission. Once successively in Shanghai, Beijing, Wuhan and other places to carry out field test. Soon after in the local telephone network as interoffice trunk trial, after 1984, gradually for the long-distance lines, and start using single-mode fiber. Communication cables with a transmission capacity greater than copper wire cable, relay section of long distance, small volume, light weight, no electromagnetic interference, since the cable transmission line shaft after 1976 has developed into the trunk, intracity relay, offshore and transoceanic submarine communication and local area network, private network and so on, and began to develop the city user loop distribution network field, provide transmission lines for fiber to the home, width generation integrated service digital network. 12 port patch panel are usually similar to the rope cable by a few or several sets of wires [Each] and twisted by at least two mutually insulated wire, between each group, and often revolve around a central twisted, the entire outer covering layer of bread with highly insulated submarine cable; specified first: distinguish the material. Cable with metal material (mostly copper, aluminum) for conductors; cable with glass fiber as the conductor. Second: is there a difference transmission signal. Cable transmission is a signal. Optical fiber transmission is optical signal. Third: there is a difference between the scope of application. The cables are used for energy transmission and low data transmission of information (such as telephone). Cable used for data transmission.

Status of wire and cable industry

Wire and cable industry is the second largest industry in China, second only to the automotive industry, product variety to meet the rate and the domestic market share of more than 90%. In the world, China's wire and cable output has surpassed the us to become the world's largest cable producer. With the rapid development of China's wire and cable industry, the growing number of new enterprises, the industry overall technological level has been greatly improved.
China's sustained and rapid economic growth, providing a huge market space for wire and rj45 pcb jack products, the Chinese market strong allure, makes the world all eyes focused on the Chinese market, in the reform and opening to the outside world in short decades, huge production capacity of China's cable industry formed to make the world with admiration. As China's power industry, data communications, urban rail transit industry, automobile industry and shipbuilding industry scale unceasing expansion, the wire and cable demand will grow rapidly, the future electric wire and cable industry has huge development potential. In 2008 November, our country to cope with the world financial crisis, the government decided to invest 4 trillion yuan stimulating domestic demand, which has about 40% for urban and rural power grid construction and transformation. National wire and cable industry has a good market opportunity, around the wire and usb 3.0 connector enterprises to seize the opportunity, meet the new round of urban and rural power grid construction and transformation.

Storage method of cable

Cable if stored for a long time, according to the position of the cable, should make the following considerations:
1, under the eaves. Barrier Terminal Block only in not exposed to direct sunlight or ultra high temperature, standard LAN cables can be applied, recommend the use of pipeline.
2, external wall. Avoid direct sunlight and man-made damage to the wall.
3, in the pipeline (plastic or metal). As in the pipe, pay attention to thermal damage and metal pipe plastic pipe.
4, application of suspension / overhead cable. Considering the cable sag and the pressure, to adopt what kind of binding mode, cable is directly illuminated by the sun.
5, directly in the underground cable trench laying, the environment is the control of the minimum range. Cable trench installation must be periodically dry or moist degree examination.
6, the underground pipeline. In order to facilitate future upgrades, replacement of

Plug-In Terminal Block

, and surface pressure and the surrounding environment isolation, auxiliary pipe isolation, auxiliary pipeline is a better method. But don't expect the pipeline will always keep dry, it will impact on the cable type selection.

Protection measures of cable

With the rapid development of power cables buried underground engineering, a higher demand on the protection of cables, cable protection sleeve is the use ofpolyethylene PE and high quality steel tube after sand blasting pretreatment, dipcoating, heating and solidifying process produced. It is the protection of wire and cable, a kind of the most commonly used electrical insulating tube. Because it hasgood insulation properties, high chemical stability, no rust, no aging, can adapt to theharsh environment and widely applied.
Use the Fiber Optical Patch Cord protection sleeve protecting cat6 network cable can achieve the followingadvantages: 1, good corrosion resistance, long service life, can be in moist saline alkali area. 2, flame retardant, good heat resistance, can be used in high temperature of 130 degrees and long term deformation, fire is not burning. 3, high strength, high rigidity. In under the road buried without a protective layer of concrete, can roll fastcable engineering construction schedule. 4, cat5e network PCB Spring Terminal Block protection sleeve for pipe or pipehas a certain flexibility, can resist the external stress and foundation settlementcaused by the destruction of the. 5, has good performance of anti interference signals. 6, smooth inner wall, do not scratch the cable. The design adopts a socketconnection, convenient installation and connection. The joints with rubber sealing ringseal can adapt to the thermal expansion and contraction, and to prevent sand entering.

How do cat6 patch panel Piggyback works ?

One commonly used solution to cable-length limitations is something called HDMI over Cat 6. ­Steven D’Addone, co-owner of Intra Home Systems in New Jersey, an installer of high-end audiovisual 4 port HDMI switch systems, swears by the technology. “We only run cat6 patch panel,” he says. Here’s how it works: A video source, such as an HD cable box, is connected to a small device­­—a “balun,” in the parlance of the trade—with a short HDMI cable. The balun usually takes the form of a small, router-like box or a wall plate. Its job is to pass the HDMI signal along to one or more cat5e cable or Cat 6 cables. (These are the same cables used to wire Ethernet networks—Cat 5e is a more common cable, but the ­newer Cat 6 standard is preferred by AV installers for its higher bandwidth.) At the receiving end, a similar box passes the signal back onto an hdmi wall plate, which then connects to your display. Now, all HDMI over cat6 patch panel baluns are not created equal. Some crudely bridge the HDMI and cat6 patch cables by relying on the signal power of the Barrier Terminal Block original video source—this limits the range considerably. Others compress and then decompress the HDMI signal, but this can cause hardware compatibility problems. D’Addone recommends a third type of system. “What seems to be the most reliable are cat5e network cable products that are high-­bandwidth and powered on both sides,” he says. These boxes, which can be found for about $100 each, create a direct bridge between HDMI and a pair of Cat 6 cables, but provide extra power to ensure the signal can travel distances up to 150 feet. Best of all, powered HDMI over Cat 6 preserves the quality of video and audio ­signals. And given the low cable price—about a dollar per 10 feet online—HDMI over Cat 6 makes the most economic sense for longer throws.

MDF industry standard definition

Patch management subsystem is the most important component, is to achieve two vertical lines and horizontal cabling subsystem cross-connect hub. MDF is usually installed in a cabinet or on the wall. By mounting accessories, patch panels can be across the board to meet UTP, STP, coaxial cable, fiber, audio and video needs. Commonly used in network 12 port patch panel engineering has UTP patch panels and fiber optic patch patch ISO / IEC 11801: 2002 patch - apply to the jumper wires connected fixtures. It enables the system to move and change the wiring is more convenient. ANSI TIA / 568-B patch panel - easy to manage cross-connect system consists of pairs of connectors composition. Twisted role in the management of patch panel in the twisted-pair cross-connect subsystems used in each room and the distribution cat6 patch panel line of the main wiring. Many models UTP patch panels, each vendor has its own product line, and the corresponding three categories, Category 5, Category 5e, Category 6 and Category 7 cables were different sizes and models, in specific projects , you should refer to the product manual, be configured according to the actual situation. Fiber optic patch panel's role is in the management of the cable will be connected subsystems, usually between the main line and distribution lines between each.
