Optical power
To measure power, attach the meter to the cable that has the output you want to measure. That can be at the receiver to measure
Measuring Received Optical Power with an Optical Power Meter
An optical power meter works by converting incoming optical energy into an electrical measurement through a photodiode detector. The detector senses the light level, and the meter displays the result in the selected unit. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power. An optical power meter measures the strength of light traveling through a fiber optic cable, giving you a reading in dBm (decibels relative to one milliwatt). TIA standard test FOTP-95 covers the measurement of optical power.
