Introduction to Optical Fibers, dB, Attenuation and Measurements
In order 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.
Decibel – gain, loss, dB, dBm, dBc/Hz
dB expresses a relative power ratio, whereas dBm specifies an absolute power level referenced to 1 milliwatt (mW). For example, an optical power of 200 mW can be stated as 23 dBm.
