The FOA Reference For Fiber Optics
We checked and the TIA and IEC standards for measuring power, FOTP-95, still defines dBm this way. That''s good, because we''re used to negative dBm being power smaller than 1mW and positive dBm

Introduction to Optical Fibers, dB, Attenuation and Measurements
To measure optical loss, you can use two units, namely, dBm and dB. While dBm is the actual power level represented in milliwatts, dB (decibel) is the difference between the powers.
