Abstract :
Optimization of an all-optical 2R regenerator at 40 Gb/s that is based on self-phase modulation in fiber is presented. The effect of fiber length, launch power into the fiber, and regenerator filter offset on the regenerator performance are investigated. We show that all three parameters can be carefully chosen to maximize the pulse regeneration. When optimized, we demonstrate an improvement in Q value of 1.5 dB.
