In the whole network wiring, a kind of wiring method is used, but
both ends have RJ-45 plug network connection, whether it is the end
connection mode A, or the end connection mode B, in the network all
are common. The order of twisted pair is corresponding to the pin
number of the RJ45 head.
The Ethernet connection of 10M Ethernet uses 1, 2, 3, 6 number of
core wires to transmit data, and 100M Ethernet lines use 4, 5, 7, 8
numbers of core wires to transmit data. Why do we now use 4 pairs
of (8 core) twisted pair? This is mainly for the purpose of
adapting to more scope of use. Without changing the infrastructure,
it can meet the wiring requirements of various kinds of user
equipment. For example, we can use one pair of twisted pair to
achieve voice communication.
The provisions of 100BASE-T4 RJ-45 for twisted pair wire netting
are as follows:
1, 2 for sending, 3, 6 for reception, 4, 5, 7 and 8 are two-way
lines.
The 1 and 2 lines must be twisted pair, 3, 6 twisted pair, 4, 5
twisted pair, 7 and 8 twisted pairs.
