Abstract :
It is experimentally verified that signal-to-noise ratio equalization in amplified wavelength-multiplexed lightwave systems can be achieved by adjusting input optical signal powers according to a simple algorithm. The experiment involved four channels spaced by 2 nm transmitted through 550 km of fiber with the aid of eight erbium-doped optical amplifiers.<>
