OPTICAL AMPLIFIER AND OPTICAL WAVELENGTH DIVISION MULTIPLEXING COMMUNICATION SYSTEM

摘要

The present invention provides a wavelength division multiplex light communication system using an optical amplifier which can amplifying and translating a multiplex light signal obtained by wavelength division multiplexing a plurality of channel light signals and can perform its control such that when the number of channels n is the maximum number of channels nmax, the total light output power Pt is maximum, Pmax and such that when the number of channels n for light signals is smaller than nmax, the total light output power Pt obtained by amplifying said multiplex light signal is substantially Pt > Pmax x n/nmax.
