Let's talk about the playing style and Tactics of RJ45 line sequence.

Let's talk about the playing style and Tactics of RJ45 line sequence.

The wiring standards of EIA/TIA define the line sequence 568a and 568b of the two twisted pair wires.
568a standard:
Green white -- 1, green -- 2, orange white -- 3, blue -- 4, blue white -- 5, orange -- 6, brown white -- 7, brown -- 8
568b standard:
Orange white -- 1, orange -- 2, green white -- 3, blue -- 4, blue white -- 5, green -- 6, brown white -- 7, brown -- 8

Note:
568a:
Green, blue, and brown
Light Color front
S3.5 (shallow) Swap
568b:
Orange, blue, and green
Light Color front
S3.5 (shallow) Swap
Record it and you will be OK!

And,In RJ45568a and 568b adopt full-duplex communication. Among them, 1 and 3 are a pair of sending or receiving lines, and 2 and 6 are a pair of receiving or sending lines.
