4. Safety
– Wear your safety glasses
– Be mindful of the sharp edges on wire
strippers and crimping tools
When working with cables always remember to…

7. 568A
CAT5 Wiring Schemes
There isn’t difference
between 568A or 568B
concerning connectivity
or performance just as
long as both ends of the
cable are of the same
wiring scheme
568A:
Commonly used in government/
federal buildings and some
large commercial
installations
568B:
This is the most commonly
used wiring scheme and found
in most residential
installations
568B

8. Making a CAT5 Cable
1. Use the wire cutters to score the cable and remove the jacket
2. Use the green pull string to expose 1 inch of wire
3. Then cut the wires with the wire cutter below the point of
the original score
4. Use the wire cutters to cut the excess jacket and shielding

9. Making a CAT5 Cable
5. Unwind the 4 pairs of wires
6. Straighten out each wire and order the pairs according to
your wiring scheme
7. Cut the wires, leaving approximately ¼ inch of wire
8. Insert the wires into the RJ-45 jack
9. Place the jack into the wire crimper and squeeze the crimper
handle

Pin
Reversed
Pair
If you do not have
access to a cable
tester, you can
easily test a cable
with a verified
internet connection
and a computer.

12. Review
Q. How many pairs of twisted wires are in a CAT5 Cable?
A. Four
Q. What are the 4 colors of wire in a CAT5 Cable?
A. Blue, Green, Brown and Orange
Q. Why do you need to use the pull string to expose more
wire after your initial score?
A. To ensure that none of the wires are nicked
Q. Which wiring scheme is more commonly used? 568A and 568B
A. 568B is the most commonly used while 568A is found in
government installations
