In 1972, Cabo-fi took the lead in launching a metal mesh cable tray in the European market. After more than 30 years of development, Cabo-fi cable trays have been laid more than 150,000 kilometers around the world, it is widely used in various engineering projects. It is not only solid and secure, but also more flexible and simple than traditional bridges. As a result, it is increasingly used in data center

During project installation, due to the limited conditions, the Network cables are all made on site. Generally, you do not need to perform an instrument test. You only need to use the indicator lights to preliminarily determine whether the network cables are turned on or off. However, the indicator lights sometimes do not reflect the network cables, some soft faults existing in the production of Network cables cannot be found at the moment. After a while, they will be gradually exposed. The foll

RJ45-type network cable plug, also known as Crystal Head, is widely used in LAN and ADSL broadband Internet users of network equipment between networks (called five-type line or twisted pair) connection. In specific applications, RJ45 plugs and network cables have two connection methods (line order), respectively called T568A Line sequence (Fig 1) and t568b line sequence (Figure 2). RJ45 type wire plug PIN number Identification method is: Hand to get

Cutting-edge Cable TechnologyAdd the colored optical fiber and oil paste to the rubber sleeve tube made of high modulus plastic at the same time, the optical fiber can be moved in the casing. The cable core is made by adding a strong core along the center of different cable casings. The cable core and protective materi

With the development of the network, as a kind of medium for transmitting data in the integrated wiring system, optical fiber is more and more used by people because it has the advantages of high transmission rate and far distance. As we all know, optical fibers are non-conductive, can be free of shock current, optical fiber cable also has good protection performance, the metal components in the cable to th

types and uses of network cables Network cable is our life in the LAN, WAN, the essential media, in the life of our common network cable mainly: twisted-pair, coaxial cable, optical fiber of these three kinds. The twisted pair is the most common in our life, and is also the main object of this article. Twisted pair is a data transmission line composed of many pa

When we use computers for work, study and recreation, what are the most feared things to encounter? I think there are a lot of users will say that the network has broken the problem, that is, the computer desktop in the lower right corner of the local connection shows the network cable did not plug the good tips, why this situation? A lot of XP SP3 system users will always inexplicably encounter this situation, but their network

the TCP/IP protocol, it turns out that there is no problem with the connections between the computers in segment 2, and network Segment 1, which is not just a break-through ping between the computers and the production machines, but also a ping between the other computers. The problem must be in net segment 1. The network Segment 2 to the production machine communication has the problem, is because from the network segment 2 to the production machine must pass through the network segment 1. Wh

1. The internal mechanism by which Linux performs write on the socket. It may involve some basic I/O mechanisms, and I can't figure out what's going on, running server and client separately, and then terminating the server so that client continues to write to the already established socket connection, and the first write successfully returns , the second execution process exits without any hint, and there's no return. Answer: After the server process is aborted, the socket is closed and fin is s

The horizontal twisted pair wires in the cabinet are located on the rear side of the Cabinet. In the past, the twisted pair wires were not organized or simply bundled before being immediately mounted to the distribution frame. At that time, from the back of the Cabinet, the horizontal twisted pair wires were hanging like waterfalls, or several nylon cable ties can be bundled on either side of the Cabinet. Everyone is concerned about the performance te

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 various natural factors and man-made damage to optical cable lines. From the past Analysi

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 Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep

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 fiber communication technology has been more and more widely used in access network tec

The world's fire standards vary, North American UL standards from high to low flame retardant, respectively: Flame Retardant CMP (suitable for ventilation ducts or air-pressurized areas) Non-combustion trunk-level CMR (for vertical trunk and horizontal area) Non-combustion commercial grade cm (suitable for horizontal area) Non-combustion general grade CMG (suitable for horizontal area) General household grade CMX (must be laid at one root level) The 20XX series cables of the United States
