Asynchronous Digital Optical Regenerator for 4 x 40 Gbit/s WDM to 160 Gbit/s OTDM Conversion.
We propose and numerically analyse an asynchronous digital optical regenerator using a single-EAM loop and a novel neighbor-combine approach. It effectively re-synchronizes input signals with arbitrary phases to the local clock, and regenerates signals with high amplitude fluctuation and polarization mode dispersion. We demonstrate the application of this regenerator for 4x40 Gbit/s WDM to 160 Gbit/s OTDM conversion.
