Optical fiber detector is also called optical power meter, which is used to measure absolute optical power or relative loss of optical power passing through a section of optical fiber. In optical fiber measurement, the optical power meter is a heavy-duty common meter, and optical fiber technicians should have one. By measuring the absolute power of the transmitter or optical network, an optical power meter can evaluate the performance of the optical device.
