A multi-channel light source generator in a WDM optical communication system, comprising:
- a pumping laser source for generating a pumping laser having a predetermined wavelength;
- a multi-channel light source generating means for generating multi-channel light sources using said pumping laser;
- a light separating means for separating said pumping laser and said multi-channel light sources;
- a demultiplexing means for separating said multi-channel light sources into a plurality of individual light sources;
- an intensity adjusting means for adjusting an intensity of said individual light sources;
- and
- a multiplexing mean for combining said individual light sources outputted from said intensity adjusting means.
A multi-channel light source generator in a WDM optical communication system, comprising:
- a multi-channel light source generating means for generating multi-channel light sources using a pumping laser and a plurality of erbium-doped optical fiber Bragg gratings;
- a light separating means for separating the signal from the multi-channel optical fiber Bragg gratings into the multi-channel light source and a pumping light;
- a reflecting means for redirecting the pumping light separated by the light separating means to the optical fiber Bragg gratings;
- a demultiplexing means for separating the multi-channel light sources into individual light sources;
- a light attenuation means for individually attenuating the light signals separated by the individual light sources so that the intensity of the light can be made constant;
- and
- a multiplexing means for combining the individual light sources outputted from the light attenuation means.
