CommScope Trunk & Distribution Cable - Manual (Page 59)

Plant Maintenance
CommScope Cable actually requires very little maintenance once installed. However, periodic inspection may
reveal small problems that can be corrected before they become large ones.
Aerial Trunk and Distribution Cable and Connectors
Worn or broken lashing wire can create serious performance problems, such as wind-caused deformation
which can impact the characteristic impedance of the cable. Loose lashing can also be the cause of jacket
abrasion which can cause water to migrate through the cable and lead to its mechanical breakdown. If this
sort of damage is detected, CommScope recommends that the entire span be replaced.
Replacing damaged connectors is best done with an extension connector. This is done because there is rarely
any excess cable in the span. While it is tempting to use some of the cable in the expansion loop, to do so
would degrade the loop and cause premature failure of the span.
Underground Trunk and Distribution Cable
Check the plant periodically for signs of physical damage or any exposed shielding. Use a TDR to see if there
is any sign of degraded performance at the point of suspected damage. Cover and protect any exposed
shield. Replace any damaged cable.
