Bad connector can be costly
NETWORK UPGRADE & SLA FAILURES• Bad connectorsmaywork at lowdata rate and fail at higher data rate• Some soils can change over time (freezing, drying, etc)
TROUBLESHOOTING ISSUES• A hidden fail will lead to troubleshootinganywhere but where the
problem is located leading to time wasted
UNACCURATE TEST RESULTS• Bad connectorswill affect test results and lead to retesting (IL, ORL &
T&D)
