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 m
There are many things worth learning about in the Metro optical fiber cable network. Here we mainly introduce the comprehensive comparison of the optical fiber lines in the Metro optical fiber cable network. How to build a Metro optical
A tester can complete the test of copper cables and optical cables, certification and documentation Record Filing automatically calculates the optical fiber margin and passes/does not pass the test results automatically at both wavelengths simultaneously measuring the two optical fiber cables stored in copper and optical
With the rapid development of broadband multimedia service and optical fiber communication technology, optical fiber communication technology has been used more and more widely in the access network. In the past, optical fiber network is mainly to meet the needs of transmission network construction, access to the layer of fiber optic
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
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

Fiber-optic communication is favored because of its advantages such as large capacity, high transmission information quality, long transmission distance, stable performance, anti-electromagnetic interference, and strong corrosion resistance. Especially in the last decade, with the increasing demand for broadband services, optical fiber communication has been vigorously developed. At present, the total length of op
performance is required. A high-speed optical fiber cable network needs to properly select the appropriate testing instrument. Laser and LED The laser emitting power is very high, and the emitted light is very concentrated, while the light emitted by the LED is usually scattered and the power is low. Compared with LEDs, a laser can send high-speed pulses, which is also the main reason for using a laser in
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 back
to be converted from multimode to Single-Mode Optical Fiber for transmission. If a digital signal is used, it can be easily transmitted. In a single input and output mode, the optical distribution amplifier can be used to configure the conversion without any baseband signal attenuation during the transmission process. If you have an existing optical fiber instal
With the extensive laying and use of optical fiber lines, the reliability and security of optical fiber communication systems have attracted more and more attention. Due to the vast territory of China, the terrain and landform are quite different, which may cause many dangerous factors to optical cable lines, including
high-speed optical fiber cables need to be correctly selected as appropriate testing instruments. Laser and LED The laser emitting power is very high, and the emitted light is very concentrated. The light emitted by LEDs is usually scattered and the power is low. Compared with LEDs, lasers can send high-speed pulses, which is also the main reason for using lasers in high-speed networks. For Single-Mode Optical
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
Currently, the access network technology is widely used, and the access network technology is also very commonly used. So I have studied the problems related to the access network technology construction planning and practical application. I will share with you here, I hope it will be useful to you. With the rapid development of broadband multimedia services and optical fiber communication technology, optical
As optical fiber transmission technology matures and the price of Optical Fiber becomes lower and lower, traditional coaxial cable transmission is increasingly unable to adapt to the development of optical network today, it has the advantages of low transmission loss, long transmission distance, working bandwidth, and
