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 d ata, though 568B is somewhat more common for installed wiring and 568A is more commo n 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. Her e’s what you will see:
