The document discusses the proper steps and procedures for fabricating a straight-through Ethernet cable, including preparing and stripping the cable, separating the wire pairs, arranging the wires in color-coded order, crimping the wires into the RJ45 connector, and repeating the process on the other end. It emphasizes safety precautions like using proper tools and avoiding horseplay. The document also includes a short quiz to test understanding of topics like wire color coding for straight-through and crossover cables.

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.

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.

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.

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.

STEP 5
 Use wire cutter to make a straight cut across the wires
1/2 inch from the cut sleeve to the end of the wires.

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.

 Take view from the top. Make sure the wires are
all the way in. There should be no short wires.

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.

Create your own functional
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.
