Paper Abstract

A hybrid fiber amplifier (HFA) comprising an erbium-doped fiber amplifier (EDFA) and a discrete compensating Raman amplifier (DCRA) can compensate both the span loss and the chromatic dispersion. The gain saturation and nonlinear effect induced in the HFA are discussed. The experimental results show that although the EDFA-DCRA has lower noise figure than the DCRA-EDFA configuration, it induces gain saturation and the nonlinear effect. When designing an HFA, the setup of the DCRA-EDFA configuration is proved a better choice.
