What is the function of the detector in an optical power meter
An optical power meter works by converting incoming optical energy into an electrical measurement through a photodiode detector. The detector senses the light level, and the meter displays the result in the selected unit. In fiber testing, the result is usually displayed as dBm for absolute optical power or dB for relative loss. Typically, it allows for power measurements only with a relatively low bandwidth, and. Below are general answers on typical components of an optical power meter product from the list of GAO Tek's optical power meter. These detectors, typically made of semiconductor.
