Making Cables (cont.)
- Step 1
Strip about 1” (25mm) of the jacket off
Don’t forget to put the boots on the cable
first of all, if you are using them

- Step 2
Untwist and reorganize the wires to reflect Cut the wires to have ½” to ¾”
one of the T568 standards (12 to 18mm) from the jacket edge
Place the RJ45 plug on the cable.
Be sure to keep the order of the wires!

- Step 3
Gently push the plug onto wires. Make sure, that all the wires
are on the end of the plug and the jacket is inside the plug’s
space for the jacket. Also look at the wires if they are still
in the correct order.

- Step 4
Plastic triangle fastens the jacket Contacts are gnawed into the wires
Push the cable end with the plug into the crimpling tool
(usually you can hear gentle click sound) and crimp
it hard enough to make good connection.
Repeat the same steps on the opposite side of the cable, and then test the cable in the cable tester.

• Test wire for correct termination of 8 wires
• Test for speed capabilities

Cabling Rules
• Try to avoid running cables parallel to power cables.
• Do not bend cables to less than four times the diameter of the cable.
• If you bundle a group of cables together with cable ties (zip ties), do not
over-cinch them. You should be able to turn the tie with fingers.
• Keep cables away from devices which can introduce noise into them. Here's a
short list: copy machines, electric heaters, speakers, printers, TV sets,
fluorescent lights, copiers, welding machines, microwave ovens, telephones,
fans, elevators, motors, electric ovens, dryers, washing machines, and shop
equipment.
• Avoid stretching UTP cables (tension when pulling cables should not exceed
25 LBS).
• Do not run UTP cable outside of a building. It presents a very dangerous
lightning hazard!
• Do not use a stapler to secure UTP cables. Use telephone wire/RJ6 coaxial
wire hangers which are available at most hardware stores.

Fiber Optic Connectors
• Terminates the fibers
• Connects to other fibers or
transmission equipment

Fiber Patch Cords & Pigtails
• Ends are typically either SC or ST
• Pigtails have connectors on only
one side and Patch Cords have it
on both sides.
• Pigtails are spliced to the fiber to
terminate the fiber Pigtail ST Multimode
• Patch Cord connects switches to
the Fiber cable
Pigtail SC Singlemode
Pigtail LC Multimode
Singlemode Fiber patch cord SC - LC
