Optical Power Meter

OPM1

Performing a test for Insertion Loss (also commonly called dB Loss or Attenuation) on a fiber optic cable requires 

an Optical Power Meter (OPM) and an Optical Light Source (OLS). This document outlines the specific steps 

which must be taken with OPM1 optical power meter to perform insertion loss testing on a variety of fiber types 

and setups.
