Chapter 4 CATV Testing
Cable Fault Finder (optional)
The Cable Fault Finder feature provides the ability to determine cable lengths up to ~135 m
and better understand in-home coax topologies. This is an optional feature.
The feature determines the distance and return loss of multiple events in a coax network by
transmitting a short pulse and then measuring the signals returned to the ONX.
Saving and syncing the cable fault results to StrataSync allows operators to better validate
subscriber drops and provides accountability into the work performed by techs and/or
contractors.
You can also run Cable Fault Finder tests in OneCheck, if enabled.
Drop Check
The Drop Check mode is intended to validate the quality of a disconnected drop cable
and distance to the end of the coax drop, looking for a single reflection to indicate it is
good.
