Pin assignments

For twisted pair cables, each pair is identified by two different colours. For

example, one wire might be red, and the other red with a white stripe. A RJ-45

connector must be fitted to both ends of the cable. The pin layout for RJ-45

connectors is illustrated below.

1000BASE straight-through cable

For 1000BASE network connections, all four pairs are used and the cable is

wired in a straight-through configuration. You can use this cable in conjunction

with the software test facility to test 1000BASE network ports. The pin

assignments are shown in the table below.
