3.1 TERMINATING CAT 5E/6 CABLES

Use standard EIA-568A or B pairing, assigning low twist density pairs

to the four center pins, and high density pairs to outside pins. Correct

pairing is vital, and should always be checked with a network cable

tester. The correct pairing is straight through, pin-to-pin, as shown.

Cat 5e/6 cable pairs have different twist densities (twist pitches). There

are two pairs with high density twist and two pairs with low density. Pairs

1-2 and 7-8 should be assigned to high density twists. Failure to assign

correct twist densities can result in image jitter. Twist densities can be

seen by stripping off about four inches of insulation.

Colors vary by manufacturer, so once you identify the high density twist

pairs, use the chart below to assign the colors to the correct RJ-45 pins.
