Abstract :
We demonstrate a polarisation-multiplexed 64 QAM coherent transmission with sub-carrier OPLL based homodyne detection utilising an optical voltage controlled oscillator (OVCO). By using the OVCO, low phase noise OPLL operation was achieved and a 120 Gbit/s data signal was successfully transmitted over 150 km with a low power penalty.
