What Is a Fiber-Optic Power Meter?

Optical power meter (optical power meter) refers to an instrument used to measure absolute optical power or the relative loss of optical power through a length of optical fiber. In optical fiber systems, measuring optical power is the most basic, much like a multimeter in electronics; in optical fiber measurement, optical power meters are commonly used meters for heavy loads. By measuring the absolute power of the transmitting terminal or optical network, an optical power meter can evaluate the performance of the optical terminal 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. ^[1]

With the rapid development of optical fiber communication technology, optical fiber communication has become the main transmission mode of various communication networks. Optical power is the most basic measurement parameter in optical fiber communication systems, and it is one of the most important parameters for evaluating the performance of optical end equipment and evaluating the quality of optical fiber transmission. Optical power meter is an instrument specially used to measure the absolute optical power or the relative loss of optical power through a section of optical fiber. It is widely used in communication trunk laying, equipment maintenance, scientific research and production. ^[3]
