insertion loss test

contamination of the optical connector end face can cause significant change in optical power, even during every connection. It is important to clean and inspect the end face of both connectors to verify before connection.

Step-1, set reference

the purpose of reference measurement is to cancel out, as much as possible, the losses caused by the various patch cables.

Step-2, measure the attenuation along a fibre link

insertion loss test from PCD to Multiport

Step-1, set reference

using two SCA-SCA patchcords and one through connector

Step-2, measure the attenuation along a fibre link 

OptiTap-SC/APC patchcord, OptiTap adapter, SC/APC-SC/APC patchcords, SC/APC adapters are required for the testingStep-2, measure the attenuation along a fibre link 

OptiTap-SC/APC patchcord, OptiTap adapter, SC/APC-SC/APC patchcords, SC/APC adapters are required for the testing
