Understanding dBm vs mW
In fiber optic testing, you often see power levels given in dBm or mW. Understanding the difference between them is crucial. These two units measure optical power, but they operate

Fiber Optic Series: Understanding dB and dBm values
Optical power measurements use the unit dBm, with the "m" denoting the reference power, set at 1mW. Thus, a source with a power level of 0 dBm corresponds to 1mW.
