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

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

At present, lan construction has been very common, and the integration of Ethernet cards on computers is already a standard configuration. The traces of LAN are everywhere around us. A simple small LAN composed of several computers in the family, large Internet cafes in public entertainment venues, campus networks on campus, office networks in the company, and so on are all examples of local area networks. Although they have various networking modes, the current LAN networking mode is still domi

Copper Cable common faults-No signal blue screen 1. Check whether the copper cables are good or bad. Method: if there is a cable of the same model and length, replace one to check whether the cable is displayed normally. If the display is normal and the copper wire is faulty, contact the dealer to change the cable. If

Category 5. Category 6, Category 6, and category 7 are basically self-styled by manufacturers. Because more than five categories of standards have already been introduced, some manufacturers have produced a type of technical indicator that is better than five categories, and 6 categories of Self-sealing; due to market competition, other manufacturers have produced a network cable that is higher than the "6 categories" Technical indicator, so it has t

1 cabling standard for copper-cable twisted pair Line 6 Integrated wiring copper twisted pair Line 6 line standard has been formally introduced. With the rapid development of computer technology, people's demand for fast communication has increased the requirement of high transmission rate of broadband belt, and the bandwidth of the integrated cabling system is increasing continuously as the communication platform of the network. Integrated wiring sys
