Optical amplifier gain characteristics measurement apparatus and method for measuring the gain of an optical amplifier

摘要

An optical amplifier gain measurement apparatus has a multi-wavelength light source means at the input of an optical amplifier under measurement, which places the optical amplifier under measurement in the saturated condition, a light source means, which generates light over a broad band for use in measurement of wavelength points other than the wavelengths of the multi-wavelength light source, an optical spectrum analyzer means 19 at the output side of the optical amplifier, and a gain versus wavelength characteristics evaluation calculation means for the optical amplifier under measurement, connected to the optical spectrum analyzer.
