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:
