Abstract
An optical transmission apparatus in which the reliability and quality of optical performance monitoring are improved. A light output unit selects and outputs light of one of a plurality of wavelengths. A digital information conversion unit converts a performance parameter for the light to digital information. A conversion map management unit manages a conversion map including a conversion format for converting the digital information indicative of values which vary according to the wavelengths of light with the same output power so that reference values at normal operation time for all the wavelengths will be the same and used for converting the digital information to a monitored value. A display control unit exercises control over the displaying of the monitored value corresponding to the digital information.
