Twisted-Pair Cabling

There are different grades, or "categories," of twisted-pair cabling. Category 5
is the most reliable and most highly recommended. Category 3 is a good sec-
ond choice. Straight-through cables are used for connecting computers to a
hub. Crossover cables are used for connecting a hub to another hub (there is an
exception: some hubs have a built-in uplink port that is crossed internally,
which allows you to link or connect hubs together with a straight-through cable
instead).
To determine which wire is wire number 1, hold the cable
so that the end of the plastic RJ-45 tip (the part that goes
into a wall jack first) is facing away from you. Face the clip
down so that the copper side faces up (the springy clip will
now be parallel to the floor). When looking down on the
copper side, wire 1 will be on the far left.
You can buy pre-made Category 5
cables, or cut and crimp your own.
Category 5 cables can be purchased or
crimped as either straight-through or
crossover. Inside a Category 5 cable are
8 thin, color-coded wires inside that run
from one end of the cable to the other.
All 8 wires are used. In a straight-
through cable, wires 1, 2, 3, and 6 at one
end of the cable are also wires 1, 2, 3,
and 6 at the other end. In a crossover
cable, the order of the wires change
from one end to the other: wire 1
becomes 3, and 2 becomes 6. See the
diagrams on the next page for more
detailed information on straight-
through and crossover
cabling.
