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. B oth are appropriate for
high s peed d ata, though 568 B is s omew hat more c omm on for installed wiring and 568A is more common in jumpers. There is no
performance advan tage either way. The only real difference between the two is the order in which the pairs are us ed (orange and
green).
Hold a c able as if to plug it into a wall jack, the locking tab down (contacts facing you). T he contacts are num bered 1-8 from left to
right. Here’s what you will see:
