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.

Optical Loss
Optical losses refer to the exponential loss of launched power during the transmission of optical signals in a fiber, primarily caused by material absorption and Rayleigh scattering.
