Investigation of multiple passes through a double-cell, self-phase modulation based regenerator

In this paper, a double-cell, self-phase modulation based optical regenerator is designed and optimised to reduce signal noise and distortion. Investigation on multiple passes through the proposed optical regenerator shows significant amplitude jitter suppression compared to single pass alternatives. Results have shown that improvement in Q-factor becomes negligible after only five loops for this system and a double Q-factor is achieved demonstrating the efficiency of the proposed scheme.
