Once you have the necessary equipment needed to create
your own T-568B network cables the installer is ready to
install RJ-45 connectors to the cable. Connectors are simple
to install by following these steps:
1.
Strip the cable jacket back at least one-half inch to
expose the inner wires. Don’t be worried about stripping
too much of the network cable jacket off since you can
always trim the wires later if necessary.
2.
Separate the ends of the cable then place them into
the connector following the T-568B standard. See
Figure 41
. Push the cable all the way into the connector.
Don’t worry about the excess wire coming out the other
end of the connector as it will be cut off after using the
crimping tool.
3.
Use the crimping tool to attach the connector and cut off
excess wire using scissors.
4.
Do these steps for each side of the cable. Once both
ends of the cable have been completed you are now
ready to test your cables.

Testing RJ-45 connectors
Testing network cables will require a hand-held meter
designed for verifying the integrity of Ethernet twisted
pair cables. These types of testers are designed for one-
person testing of installed cable. Reasonably priced units
are available at electronics stores. Testing is simple and
straightforward. Simply follow these steps:
1.
Inserts one end of the cable into the meter and attaches
the remote adapter on the other end.
2.
Press the meter test button. The meter will test the
twisted pair cable for opens, shorts, reversed, crossed,
and split pairs.
3.
Repeat RJ-45 connector installation steps and repeat
testing for cables not passing initial testing.
4.
The installer is now ready to connect cables to digital
switches and install them into the switch box.
