Ethernet cables fit into two categories:
z
Straight-through cable. At both ends, the twisted pairs are
crimped in the RJ-45 connectors in the same sequence. The
cable is used for connecting different types of devices, such
as connecting a terminal device (PC for example) or H3C
SecPath F100-C to a Hub or LAN Switch. The
straight-through cable is shipped in company with the H3C
SecPath F100-C.
z
Crossover cable. At both ends, the twisted pairs are crimped
in the RJ-45 connectors in different sequence. The cable is
used for connecting devices of the same type, such as
connecting two PCs, two H3C SecPath F100-Cs or a PC to
a H3C SecPath F100-C. You can make the crossover cable
by yourself.

In preparing network cables, shielded cables are preferred for its
electromagnetic compatibility.
