OPTICAL SIGNAL AMPLIFICATION CONTROL SYSTEM

摘要

Disclosed is an optical signal amplification control system for amplifying in the lump a wavelength-multiplexed signal that several optical signals with different wavelengths to be transmitted through an optical fiber cable are multiplexed, the system having: means for detecting always the number of the different wavelengths multiplexed in the wavelength-multiplexed signal; and means for amplifying in the lump the wavelength-multiplexed signal; wherein the optical signal amplification control system controls the amplifying means to amplify in the lump the wavelength-multiplexed signal up to a desired level according to the detected number of the different wavelengths.
