网线的接法568a和568b线序详解（Wiring method 568a and 568B line sequence detailed explanation） Wiring method: 568A and 568B line sequence detailed explanation Shenzhen computer parts wholesale network / 2009-07-30 568A: white and green green orange blue and white | | | | | | orange white blue white brown | Brown 568B: white orange orange white green blue | | | | | | white blue green white brown | Brown Straight line: used for interconnection between different devices (switch -PC) 568B-568B For the same line: interconnection between devices (PC-PC, switch - switch) 568A-568B ******568A 568B sorting and differentiation details (5, Passages, in, all) One The order of 568A is from left to right: white, green, green, white, orange, blue, white, blue, orange, white, brown, and brown. 568B: white, orange, orange, white, green, blue, white, blue, green, white, brown, brown. The so-called cross line refers to: one end is 568A standard, and the other end is 568B standard twisted pair. Direct line refers to both ends of the 568A or 568B standard twisted pair. By the way, a lot of friends are doing RJ45 head, just to ensure that the line at both ends of the corresponding order, but did not follow the 568A/568B cable standard to do. Although this can connect to the network, but this line of anti-interference is very poor, often such as transmission speed is slow, the network is good or bad situation. I hope that when you do network cable must be done according to standards, and according to the actual engineering experience, the length of the network is best not less than 1.5 meters, which is necessary to improve the stability of the network! Next, lets see how to choose straight and twisted wires. Direct wiring is used when the following devices are interconnected: 1. connect the switch or HUB to the router; 2. computers (including servers and workstations) are connected to switches or HUB. When these devices are interconnected, cross lines must be used: 1. switches and switches connect th
