WebMay 26, 2024 · The optical power meter reading expressed in units of dBm on the OPM screen is an intuitional way to measure optical power. The “m” in dBm refers to the reference power which is 1 milliwatt. Thus a source with a power level of 0 dBm has a power of 1 milliwatt. Likewise, -10 dBm is 0.1 milliwatt and +10 dBm is 10 milliwatts. WebThe optical power meter usually reads in dBm for power measurements or dB with respect to a user-set reference value for loss.
