The basic process is straightforward: turn the meter on, set it to the correct wavelength, clean your connectors, plug in, and read the display. 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). " Optical loss is measured in "dB" which is a relative measurement, while absolute optical power is measured in "dBm,".
