568A
CAT5 Wiring SchemesThere 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
Making a CAT5 Cable1. Use the wire cutters to score the cable and remove the
jacket2. Use the green pull string to expose 1 inch of wire3. Then cut the wires with the wire cutter below the point of
the original score4. Use the wire cutters to cut the excess jacket and shielding
Making a CAT5 Cable5. Unwind the 4 pairs of wires6. Straighten out each wire and order the pairs according to
your wiring scheme7. Cut the wires, leaving approximately ¼ inch of wire8. Insert the wires into the RJ-45 jack9. Place the jack into the wire crimper and squeeze the crimper
handle
Let’s Make a Cable!
When TESTING a CAT5e Cable, you will need:
Testing A Cable
Working Cable
Open 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.

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 568BA. 568B is the most commonly used while 568A is found in government installations
