After the installation of the cable wiring system, the link transmission characteristics need to be tested, among which the main test items are the attenuation characteristics of the link, the insertion loss of the connector, the return loss and so on. The following is a brief introduction to the measurement of key physical parameters of optical cable wiring and troubleshooting and maintenance in the networ

As an Android technology home, USB OTG is what you must understand, so-called USB OTG is you can use the phone or tablet to charge, and the computer to transfer data from the Micro USB interface to connect other USB peripherals, such as gamepad, mouse, keyboard, The USB stick even moves the hard drive (of course you need extra power). and a USB OTG data cable is a must-have tool.Finished product effectThere is no clear standard for what USB peripheral

USB cable on the market, its name is "with magnetic ring, with screen", but 3 meters will not work. No MP4 can be recognized for a 5-meter connection. There is no 10-meter USB extension cable on the market, even if there is a sky price.Is the most common USB extended cable. Valid at most 3 meters.10 meters of cost-effective cables are cables, which are eight core

First of all, our most common network cable has 3 kinds The first is: straight-through cable The second type is: Crossover cable The third is: reversing the cable The first is through the cable, straight line, also known as the normal line or standard line, both ends of

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 Fiber Links, Fabry-Perot laser light sources are usually used. The new VCSEL (Vertica

When dealing with computer networks, it is inevitable that network cables should be used frequently. In fact, the production of Network cables is very simple, that is, to insert the 4-to-8-Core Cable of twisted pair wires into the crystal head according to certain rules, therefore, the materials required for the production of such network cables only need twisted pair wires and crystal heads. The required tools are also relatively simple. Generally, o

In the installation of the project, due to the limited conditions, are on-site production of network cable, generally do not use instrumentation, only through the pilot indicator to determine whether the guide, but the indicators can not really reflect the quality of the network cable, the production of some of the soft fault is not found, after a period of time will gradually exposed, The following are som

Some people often ask me some questions about the network cable. When I talk with them, I find that the network cable errors are extremely common. The root cause is that the line makers do not understand the principle, so I think it is necessary to write something to talk about.First, let's talk about differential transmission. The so-called differential transmission means that the sending end transmits an

Now, Gigabit Networks are becoming more popular, but the practice of Gigabit Networks is not widely understood by many friends. Hope to help you. The gigabit 5 category or over 5 category twisted pair wires are in the same form as the 10-Gigabit network cable. They are also divided into two types: pass-through and crossover. The straight-through network cable is exactly the same as what we usually use. How

The on-site test of optical cable construction is very important. It is used to prepare for the overall commissioning of the optical terminal. The optical fiber test items in the optical fiber have the measurement of transmission attenuation. for Multimode Optical Fiber, test the baseband response when necessary. The purpose of the single-disk optical cable test is to ensure the quality of the factory produ

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 strong anti-interference ability, making it the most ideal carrier for optical network communication. The optical fiber is made of extr

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 optical fiber cables in China's communications industry has reached more than 2 milli

Document directory Cause: Process: Conclusion: Cause: My colleagues reported that the Local Area Network could not be mounted. After reading the past, they found that the prompt "the network cable is not plugged in". I suspect that it is not plugged in, plug in, restart, and reinstall the NIC Driver. My colleague reported that the network cable could be connected to the LAN using a laptop. After

verify the connectivity between each pin end and end of the cable link and check the winding problem. Any wrong wiring format, such as open circuit, short circuit, cross-connection, reverse connection, and string winding, should be able to be detected. Attenuation is another important parameter for determining the performance of the cabling system. Any electronic signal from the signal source will cause energy loss during transmission, which is no ex
