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
The application of optical fiber cables in telecommunications and long-distance communication networks has become very popular and mature. In recent years, with the application of Gigabit Ethernet and the gradual arrival of 10-Gigabit Ethernet, more and more applications of optical cables in LAN have been made. In recent years, local area networks, man networks, campus networks, and campus networks have alm

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
Nowadays, optical transceiver network devices are increasingly used in our network engineering. They are used in small-scale optical fiber trunk connection solutions, so it is better to use optical fiber interfaces for switches in large-scale optical fiber trunk. Because of the various types of
The metropolitan area Optical cable line is mainly the pipeline optical cable, supplemented by the aerial and other laying way very few optical cables, its characteristics are: The line section is relatively short, can be divided into local trunking, user access network backbone and user to introduce optical cable,
Remember to enable the software drive and enable it again in CMOS to speed up the startup. The software drive is available, but not the optical drive. I saw the CD drive detected on the motherboard in CMOS. I think it must be a system problem. I checked the information on the Internet and found that, it is likely that the driver in the ide ata/atapi controller in the Device Manager has a problem.
Program The device type in is changed to none. It turn
The test of the optical cable cabling system is a necessary step for project acceptance. It is also the final process for the project contractor to honor the contract with the real estate owner. Only after the system test is passed can the cabling system be completed.
The connectivity of devices is the most basic requirement for wiring system testing. The effectiveness of jumper systems can be easily tested. It is relatively difficult to test the indi
