PURPOSE: A method for monitoring an optical wave length using temperature change character of a waveguide a grid, is provided to apply temperature change to the waveguide, inputting an optical channel to be monitored, in a situation perceived a relation between before/after change of the temperature, by changing the temperature of the waveguide. CONSTITUTION: A method for monitoring an optical wave length using temperature change characteristic of waveguide, a grid is followed below. A temperature of optical wavelength distribution reverse multiplexer is changed, to change penetrated characters to an optical wavelength. The changed degree is memorized on a memory element, and optical channel wavelength values of wave distribution multiplex optical communication system are monitored simultaneously. Further, from the changed degree, optical channel wavelengths are fixed at regular values simultaneously. The waveguide is used as the optical wave length distribution reverse multiplexer. The optical wavelength reverse multiplexer of optical fiber grid structure is used as the optical wave length distribution reverse multiplexer.
