Cable Fabrication
Proper Steps and Procedures
STEP 1
Using a Crimping Tool, trim the end of the cable you’re
terminating, to ensure that the ends of the conducting
wires are even.

Cable Fabrication
Proper Steps and Procedures
STEP 2
Strip off approximately 1 inch of the cable’s jacket, using
a modular crimping tool or a UTP cable stripper. Be
careful not to damage the inner conducting wires.

Cable Fabrication
Proper Steps and Procedures
STEP 3
Separate the 4 twisted wire pairs from each other, and then unwind
each pair, so that you end up with 8 individual wires. Flatten the
wires out as much as possible, since they’ll need to be very straight
for proper insertion into the connector.

Cable Fabrication
Proper Steps and Procedures
STEP 4
Moving from left to right, arrange the wires in a flat, side-by-side
ribbon formation. The color order is important to do this correctly.

Proper Steps and Procedures
STEP 6
Hold the RJ45 connector so that its pins are facing away
from you and the plug-clip side is facing down, carefully
insert the wires into the connector. Each wire fits into a
slot in the RJ45 connector.

Proper Steps and Procedures
STEP 8
Insert the prepared connector/cable assembly into the RJ45 slot in
your crimping tool. Firmly squeeze the crimper’s handles together
until you can’t go any further. Release the handles and repeat this
step to ensure a proper crimp.

STEP 9
After completing the fabrication on the first end of the
cable, repeat all steps on the opposite end of the cable
using the other wire color order.

STRAIGHT-THROUGH ETHERNET CABLE
• Each group will be provided with an Ethernet Unshielded Twisted
Pair (UTP) Cable, RJ45 Connector and Crimping tool.
• Each member of every group will perform specific steps in
Fabricating a Straight-Through Cable by pair.
• While one group member is performing, the other group
members are allowed to guide their groupmate.
• Each group should let the person finish the steps assigned to
him/her before the other member take-over for the next steps.
• When the fabrication is done, submit your output.
• Your outputs will be checked using a LAN tester.
