Service Loops Tested

By John Scanlan, Published Apr 18, 2022, 09:33am EDT (Info+)

Many installers leave significant service loops, but some are concerned that this will create performance issues. We tested various service loops to determine if they have an impact on cable performance.

IPVM Image

For this report, we tested several drops at distances of 50', 75', 150, and 300' without service loops, with 10' and 20' service loops, and with the cuts of cable completely coiled.

Inside this report, we examine:
