ABSTRACT:
In a wavelength multiplexed optical transmission system incorporating a concatenation of optical amplifiers the multiplexed signal passes through a limited number of amplifiers in which all channels are amplified together, after which, at the next amplifier, the signal is demultiplexed, each channel is separately amplified, and then the channels are remultiplexed.
