About 568A and 568B on an Ethernet connector RJ-45
TIA/EIA-568A and -568B are two standards for connecting Category 3 and Category 5 wire to connectors. Both are appropriate for
high speed data, though 568B is somewhat more common for installed wiring and 568A is more common in jumpers. There is no
performance advantage either way. The only real difference between the two is the order in which the pairs are used (orange and
green).
Hold a cable as if to plug it into a wall jack, the locking tab down (contacts facing you). The contacts are numbered 1-8 from left to
right. Here’s what you will see:
