Post-Splicing Procedure
The post-splice procedure involves the following steps:
1 Starting at the cable stub butt of the CO cable stub, wrap the pairs on one side of the screen with
3
/
4
-inch,
self-bonding rubber tape. Overlap the tape by one-half its width, as shown in Figure 12 .
2 Repeat Step 1 , wrapping the pairs on the other side of the screen of the CO cable stub in the same manner.
Figure 12. Post-Splicing Procedure
3 Starting at the cable stub butt shown in Figure 12 , wrap the pairs on one side of the screen with 2-inch,
pressure sensitive, aluminum tape. Overlay the tape by one-half its width and form the tape in place.
Aluminum tape provides electrical isolation from outside EMI sources. For these applications, dress out the
splice per local practices.
Aluminum tape may present a potential shorting hazard when splicing paper-insulated cables.
