      Optical Module Output Optical Power

      The output optical power (Output Power) refers to the average output optical power of the light source at the transmitting end of the optical module, also called the output optical power, which can be understood as the intensity of light. Formula: P(dBm)=10Log(P/1mW) The unit is W or mW or dBm. (...
