Optical power meter

Optical power meter (optical power meter) is an instrument used to measure optical power. It can be used for direct measurement of optical power and relative measurement of optical attenuation. Basic test equipment necessary for maintenance and other departments. [4]
In optical fiber systems, measuring optical power is the most basic, much like a multimeter in electronics; in optical fiber measurement, an optical power meter is a heavy-duty meter. By measuring the absolute power of the transmitter or optical network, an optical power meter can evaluate the performance of optical equipment. Using an optical power meter in combination with a stable light source can measure connection loss, verify continuity, and help evaluate fiber link transmission quality
