This article introduces the optical fiber cabling system. Many people may not know about the optical fiber cabling system yet. I believe you will have a rough understanding of the optical fiber cabling system after reading this article, I hope this article will teach you more things. After the optical cable cabling system is installed, You need to test the link transmission characteristics. The main test items are the attenuation characteristics of th

Data center energy saving does not affect network cable cooling At present, the data center's heat dissipation is generally designed to separate hot and cold channels, that is, the cold and hot channel control technology, to isolate the cold and hot channels, to prevent mixed cold and hot air, the cold channel helps the device get the air-conditioning flow, and then the hot air flow is discharged through the hot channel. In this mode, the data center

A lan is to connect individual computers or terminals using networks to exchange information and share resources according to certain protocols. Commonly used network cables include twisted pair wires, coaxial cables, and optical fiber cables. Twisted Pair wires can be divided into shielded twisted pair wires (STP) and unshielded twisted pair wires (UTP) based on whether they are added with the screen layer of a wire mesh ). Most local networks use unshielded twisted pair wires (UTP-unshielded t

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

Lower signal attenuation can be achieved through the use of copper media cables of a slightly heavier specification, with a diameter between 0.5mm (24AWG) and 0.6mm (23AWG. Two available cables are included in the scope of TIA's 6 standard sp

On my first day, I took my laptop and my CB back to my hometown. I encountered the following scenario, so I wrote this tutorial.My sister-in-law's house is downstairs. I live on the 5th floor, while my sister-in-law lives on the 4th floor. Her house has network and wireless routes. I use my own book to access the Internet in my house on the 5th floor at night, I was connected to the Internet, but my CB didn't have a wireless network card and a network cable
