In accordance with the normal application of the topology of computers, routers, cats connected, if the corresponding router LED is not bright, this problem may be connected with the network cable, fault, port failure and other reasons, this article provides detailed troubleshooting ideas. The WAN port LEDs are not lit 1, check whether the WAN port wiring, check and WAN port connection of the cat is power (network

First, the preface In the context of the large increase of global data traffic, data center construction tends to the direction of cloud computing, while the cloud Computing data Center will use 10G, even 40g/100g and other high-speed network applications based on fiber transmission, and the application of virtualization technology also put forward higher requirements for network transmission, Presents new opportunities for the application of optical fiber systems. While China's national standa

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

The UTP and unshielded FTP for category 5 and Category 6 copper cables have already reached a consensus in the industry. After the promulgation of the 10GBase-T standard, the battle for shielding and unblocking 10g copper cables is now in front of us. When more and more 10g copper cable products are available and more mature, are they shielded or unshielded? Debate stems from out-of-Line crosstalk Before the promulgation of the 10GBase-T standard, IEE

specific applications to test the quality of cable jackets. For details, see: CMP: Fill-level communication cable, which is the highest cable Safety Grade and has a perfect flame retardant capability with very low smoke and toxin emissions. According to UL's definition, a bundle of CMP cables must be self-extinguished when the fan is forced to burn in dense comb

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

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
