In the construction of digital community, the choice of cable is one of the most important links. At present, several schemes are: 1, twisted pair, 2 coaxial cable, 3, optical fiber. From the practical application, because the price factor of twisted-pair cable has advantages over the latter two kinds of cable, but bec

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep

Network cable Creation Method How to create a network cable?Creating a network cable is an essential step for building a LAN. Next we will introduce how to create a network cable.Main Line (Standard 568b): the two ends of the line Order is the same, the line order is: White orange, orange, white green, blue, white

A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshielded twisted pair wires (UTP-unshielded t

What is Smart Community cable used? In the construction of digital communities, cable selection is one of the crucial links. Currently, several schemes are adopted: 1. Twisted Pair wires; 2. coaxial cables; 3. optical fiber cables. In terms of practical application, twisted pair wires have advantages over the last two types of cables due to price factors, but are not suitable for video use. In addition, whe

Problem DescriptionInhabitants of the Wonderland have decided to hold a regional programming contest. the Judging Committee has volunteered and has promised to organize the most honest contest ever. it was decided to connect computers for the contestants using a "star" topology-I. e. connect them all to a single central hub. to organize a truly honest contest, the Head of the Judging Committee has decreed to place all contestants evenly around the hub on an equal distance from it.To buy network

One: For the use of desktop cable Bridge 2 first, using the desktop Bridge wireless router hardware connection: Assuming that a router is bridged router, b router is now to bridge a router router, then use a network cable to connect any LAN port on a router to the WAN port on the B router, Then use a different cable to connect the LAN port on the B router to the

Talking about Cable Modem broadband access technology and its maintenance when talking about Cable Modem broadband access technology and its maintenance, we need to first understand what Cable Modem?1 Cable Modem the concept Cable Modem is also known as a

Currently, cabling system installers and network technicians are still using older Cable Fault Locating tools based on analog technology that was just 40 years ago. Even tools that use these simulation technologies often identify cables incorrectly or cannot discover signals in common work environments, they are the only choice. This is the case until today. R D engineers of fluke networks have applied decades of specialized

A few years ago, people thought that the unshielded twisted pair copper cable had reached its limit in the fifth category of MHz. Many users and manufacturers turned their attention to the optical fiber and thought that the optical fiber is an inevitable transitional path for IT facilities. The optical fiber solves the disadvantages of unshielded twisted pair wires in various aspects: it has higher bandwidth, longer distance, higher security, complete

Several problems should be noticed in the connection of optical cable. 1. Note the depth of the knife when opening the optical cable. The key to open the outer sheath of optical cable is to master the depth of the cutting tool, otherwise it is easy to break the fiber. In the actual operation, should rotate the sheath cutting knife, while observing the incision,

The cable system is designed and constructed for the convenience of the landlord, but the landlord and the facility manager usually have no knowledge or measure of the interior of the room to ensure the proper design and installation of the cable system. General contractors and construction managers are generally not experts on telecommunication cables, nor can they take into account the best interests of t

main driving force of Wan Xiaotong Cable Ethernet is to reduce the cost of Ethernet network, for a wide range of implementation of Gigabit Ethernet, the use of optical fiber transmission solution has been proved to be too expensive, so based on the copper cable solutions can be developed and applied. Wan Xiaotong Cable Ethernet Recently, the IEEE is working on

In Windows 7, when Ipad2 is connected through a data cable, iTunes cannot find the device. Fault symptom: After Ipad2 is connected through a data cable in Windows 7, iTunes cannot find the device. Cause Analysis: Operating System Setup problems, or IOS system problems, or ipad2 hardware problems: 1. When IPAD2 is able to boot normally and connect the data line to the PC, in this case, no matter whether the
