The irresistible growth in capacity demand for optical transmission systems calls for an increase in both channel granularity and bit rate, while maintaining signal quality. The document reviews recent developments in the field of all-optical regeneration and show its potential to meet the challenge with cost-effective implementation. We also report a 160Gbit/s all-optical regenerator based on the simultaneous optical regeneration of four 40Gbit/s WDM channels in a single polarization-insensitive modulator chip by using an all-optical cad simulation tool. Regenerated transmission with 0.2(bit/s)/Hz spectral efficiency is achieved over 10,000km distance.
