RJ45 8P8C Network Ethernet Lan Cable Cat 5e Patch Cord

Twisted pair is a universal wiring made by winding two insulated wires together according to certain specifications (usually clockwise), and belongs to the transmission medium of information communication networks.

Twisted pair cables were mainly used to transmit analog signals in the past, but now they are also suitable for the transmission of digital signals.

In 100 Gigabit Ethernet (Fast Ethernet, 10/100M Ethernet), only four wires 1, 2, 3, and 6 are used to reduce electromagnetic interference through differential signal transmission. Among them, 1 and 2 are TX (sending) (twisted together), and 3 and 6 are RX (receiving) twisted together. Therefore, a parallel line is a method of connecting EIA-568-A or EIA-568-B at both ends, while a jumper is a method of connecting EIA-568-A at one end and EIA-568-B at the other end.
