wear safety glasses when doing any of
these exercises and dispose of all scraps
properly.

Exercise
1:
Cut off a length of Cat 5e cable about 1meter or 3 feet
long
2. Strip
~50mm - 2" - jacket from one end of the cable
as you did in the previous exercise
3.
Untwist all the pairs leaving about 13mm or 1/2 inch
twisted
4. Look
closely at the jacks. The color code for each wire
location is shown on the jack. There are two shown "A" for
TIA-568A" pinout and "B" for TIA-568B"
pinout. Since we did the plug in TIA-568B, we
must to do the jack also as TIA-568B, so follow that color
code.The color codes may not agree with the color codes in
drawings for cables or plugs because jacks often have
twists inside the jack to prevent crosstalk, so the wiring
is not the same as the standard. Use the color codes on
the jack.
5.
Following the color codes, press each wire into the right
location on the jack with your fingers.
6. Examine the punchdown tool.
Note the blade has two sides, one will punch down wires,
the other side will punch down thewire and cut off the
excess wire. When you use this tool, make certain the cut
side of the tool is on the side where you want to cut off
the excess wire!
7. Using the punchdown tool, punchdown each wire and cut
off the excess wire.
8. Once you have completed this jack, follow the
procedures again to install a jack on the other end of the
cable.
9. When both jacks are installed go
to the wiremapping
exercise to test your cable.
You
have successfully completed this exercise when you
have been able to strip the jacket and both buffer
coating layers from the fiber without breaking the
fiber.
Clean up all your fiber
scraps and dispose of them in a container like a used
take-out coffee cup marked "Fiber Scraps"!
After successfully stripping fiber several times, fill
