Optical Test Procedure
This section describes the methods applied to test fiberoptic cable’s optical insertion loss and return loss.
Fiberoptic Cable Test
Due to the extended distances that analog signal transmissions travel on cable, the major
challenge is to determine the status of the cable.
In order to determine that the cables are functioning, technical personnel need to
perform optical power tests.
The optical power tests covered in this document are:
•
Optical insertion loss measurement test
•
Optical return loss measurement test
In order to explain the testing procedures, the terms related to these tests need to be
explained.
