网线水晶头接法（Wire mesh crystal head method） Wire mesh crystal head method What is the difference between the 568A standard and the 568B standard interpolation method (not interpolation, is it property)? Are two kinds of plug in the line can access the Internet? And what do you mean by 1, 2, 3, 6? What is 1236? Standard 568B: orange, white, --1, orange, --2, green, white, --3, blue, --4, blue, white, --5, green, --6, brown, white, --7, brown --8 Standard 568A: green, white, --1, green, --2, orange, white, --3, blue, --4, blue, white, --5, orange, --6, palm white, --7, brown --8 Whats the difference between 568A and 568B? The latter is the upgrade and perfection of the former, but the latter is still in the draft stage, including the definition of the permanent link and the six types of standards. In addition, in the construction of integrated wiring, there are two different 568A and 568B wire laying methods, the two methods do not affect the performance, but it must be stressed that in a project can only use one kind of wire laying method 10M Ethernet cable using only 1, 2, 3, 6 the number of wire transfer data, namely 1, 2, 6 for 3 for sending, receiving, according to the color: Orange White and orange two used to send; green white, green and two for receiving. In addition, four, 4, 5, 7, 8 are two-way lines, play a secondary role in eliminating interference, in 1, 2, 3, 6, there are some invalid connections automatically fill up. If there is no other high voltage current on the line, its OK to use the two pairs of wires. But Gigabit networks must be used. 100M and 1000M network cards need to use four pairs of wires, that is, the 8 cores are all used to pass data. Because 10M network card can use 100M way to make the network cable, and twisted pair also provides four pairs of lines, so in daily life no longer distinguish, 10M network card can also by 100M way to make network cable. Therefore, single access 1, 2, 3, 6, can only meet the speed requirements of 10M Ethernet,
