Twisted-Pair Cabling, Crimping Your Own Network Cables

Page 28 highlights

Instant BroadbandTM Series Twisted-Pair Cabling There are different grades, or categories, of twisted-pair cabling. Category 5 is the most reliable and is highly recommended. Category 3 is a good second 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). detailed information on straight-through and crossover cabling. You can buy pre-made Category 5 cabling, 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 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.

There are different grades, or categories, of twisted-pair cabling. Category 5
is the most reliable and is highly recommended. Category 3 is a good second
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).
You can buy pre-made Category 5
cabling, 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.
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.
