sun and rain, the water is split from the thin area of the outer skin, make the external conductor metal layer or metal mesh) corrosion. When the fault is checked with A multimeter, If the measured loop resistance is much higher than the original cable loop value, it proves that the outer conductor is seriously corroded. If the measured loop value is infinite, it indicates that the outer conductor is broken after corrosion. In short, there are many methods for detecting coaxial cables. As long

Optical fiber is short for optical fiber. It consists of a fine glass wire with a diameter of about 1mm. Because of its high transmission bandwidth and communication capacity, especially not subject to electromagnetic interference, it is favored by the enterprise LAN Integrated Wiring. Based on the comprehensive wiring specifications and the characteristics of Enterprise LAN construction, the selection of

The optical fiber access network is worth learning a lot. Here we mainly introduce the position of optical fiber cabling in the optical fiber access network, including the latest development of the optical fiber cabling system and the progress of the optical fiber connection

1 Overview At present, after completing the network transmission infrastructure construction, China's major communication operators have made full use of the bandwidth of the existing transmission link and sought new value-added communication services to increase business profits. The implementation of e-commerce and e-government, as well as the development of telephone bars, Internet cafes, and other small-and medium-sized Telecom customers have seen the recent boom in Man and the increase in

As a synonym for high-speed and effective network, optical fiber networks are widely used in communication systems. Achieving transparent and high-survivability all-optical communication networks is the development goal of broadband communication networks. As an important basic technology in all-optical communication networks, the development and application of

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 wir
