To avoid split pairs, tie or band the ends of the Group 1 and Group 2 pairs. Cut off pair ends and the cable
butt to aid in the removal of grease.
5
Separate pairs between the tied ends and the cable butt to aid in the removal of grease.
6
Remove grease by wiping the tied ends and the cable butt with a clean cloth or paper towel.
7
Keep cable pairs dry and cover the exposed splice to protect it from the weather if it is left unattended prior
to completion.
Splicing Procedure
Certain applications involve splicing the cables on the HRE-712. The following section describes splicing
procedures and wire list information.
1
Splice the cable stub to the main cable using the wire identification information in
2
Visually inspect each splice for split pairs, opens, and shorts.
3
Connect the CO side of the main cable to the CO side of the cable stub with a straight splice, as shown in
If the air temperature is low, warm the cable pairs to aid in removing grease by cleaning the stub
in a heated enclosure or by using a heat gun to apply warm air to the pairs. Avoid applying
excessive heat, which could deform the insulation on the pairs.
Do not cross-splice defective pairs between enclosures. These pairs are referred to as
wandering pairs and may cause problems.
