TP Cable The TP cable has eight wires arranged in four pairs of twisted wires. Different color codes exist
for the coding of the wires, the coding according to EIA/TIA 568, version 1, being the one most
commonly used. In this code, the individual pairs are coded with blue, orange, green and brown
color. One wire of a pair is unicolored and the corresponding second wire is striped, the respec-
tive color alternating with white. For shielded cables, a distinction is made between cables that
have one single shield around all pairs of wires and cables that have an additional individual
shield for each pair of wires. The following table shows the different color coding systems for TP
cables:

Two general variants are distinguished for the pin assignment of the normally used RJ45 con-
nectors: EIA/TIA 568 version A and version B. The wiring according to EIA/TIA 568 version B is
the one most commonly used.

2.5.4.5.3 Cable Types
Straight-through For networks with more than two subscribers, hubs or switches have to be used additionally for
cable distribution. These active devices already have the crossover functionality implemented which
allows a direct connection of the terminal devices using straight-through cables.
