Application of preemphasis to achieve flat output OSNR in time-varying channels in cascaded EDFAs without equalization.

Original language description

We present a new method for optical signal-to noise ratio (OSNR) equalization of wavelength division multiplexed (WDM) channels at the end of a cascade of several erbium-doped amplifiers (EDFAs) by use of preemphasis, as well as the proper chice of EDFAdesign parameters. Identical OSNR at the end of the cascade ensures better signal detection and quality of service. The dynamics of the equalizing method have been demonstrated by simulation for single- and double-stage amplifier design.
