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 co nnectors. Both are appropriate for
high s peed data, though 568B is s omew hat more common for installed wiring and 5 68A 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:
