All-Optical 3R Regeneration at 40 Gb/s in a Recirculating Loop Utilizing Raman Amplification, Nonlinear Phase Modulation, and Offset Filtering

摘要

The performance of an all-optical 3R regenerator for 40 Gb/s RZ-OOK signals is investigated experimentally using a recirculating loop. A power penalty of 1.2 dB is obtained for 100 loops (8,000 km).
