SOA-based Clock Recovery and Demultiplexing in a Lab Trial of 640- Gb/s OTDM Transmission over 50-km Fibre Link

We report for the first time SOA-based clock recovery and demultiplexing of 40-Gb/s channels from 640 Gb/s OTDM signals over 50-km link. The system operates at low power and has the potential to be integrated.
