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

Culvert cables are not easy to bury and difficult to maintain. The problem can be solved by adopting the steel pipe protection and the reverse buckle of the cable trough. Signals and cables pass through the culvert and cannot be dug deep and buried as usual. Therefore, the cables are exposed, which facilitates protection, but cannot receive good results. The cable trough and the cover plate are used to pro

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

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

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

There are two routers in the home want to connect to use, or use someone else's network, want to pick up a router to use WiFi internet access, using a router cascade can connect two routers, convenient use of WiFi router. There are two ways to connect a two router: The first way: the route mode Cascade, the second level router and the superior router all have the routing function, two routers are two independent LAN The second way: switch mode cascade, the second level router is equivalent to

Network cable classification and purchasing A network cable in the broad sense includes coaxial cables, telephone lines, optical fiber cables, and twisted pair wires. According to the Ethernet standard set by IEEE, twisted pair wires are most suitable for common LAN with a star topology. The twisted pair uses rubber as the Housing material, and contains 4-to-8 copper core plastic wires of different colors
