The optical power meter

烟士批灵

        is used to measure the absolute optical power or use a section of optical fiber optical power loss of the instrument. In the optical fiber system, measure the optical power is the most basic, is very much like electronics, universal meter; In the optical power meter in optical fiber measurement is a common table in heavy load. By measuring the transmit-end machine or absolute power of the optical network, an optical power meter to be able to evaluate the optical performance of the end device. Use an optical power meter used in combination with stable light source, it can measure the connection loss, and check continuity, and helps evaluate the transmission quality of the optical fiber link.
