Three-level-control EDC technique using simple eye monitor for access networks

A three-level-control electronic dispersion compensation (EDC) technique using a simple eye monitor detecting the duty ratios of the received signal is proposed and demonstrated. The EDC prototype can compensate for the chromatic dispersion of 40 km singlemode fibre and realise a cost-effective 10 Gbit/s transceiver utilising a directly modulated laser diode for access networks.
