Feed Forward Noise Suppression for ASE-Seeded WDM Systems

We investigate feed forward noise suppression for ASE-seeded WDM systems in relation to its limitations. In particular, limitation factors such as background ASE of reflective light sources and filtering effect are thoroughly investigated. We also measure the penalty induced by feed forward paramete...

Description
Summary:We investigate feed forward noise suppression for ASE-seeded WDM systems in relation to its limitations. In particular, limitation factors such as background ASE of reflective light sources and filtering effect are thoroughly investigated. We also measure the penalty induced by feed forward parameter variation from the designed value. Although the BER performance is improved by noise suppression, the statistical noise distribution change reduces the effectiveness of noise suppression.
