High performance 70 Gbit/s SPECTS optical-CDMA network testbed

Error-free operation of an optical code division multiple access (O-CDMA) network testbed with seven simultaneous users at 10 Gbit/s/user distributed in two time slots is demonstrated. The O-CDMA network testbed overcomes the key challenge of multi-user interference by adopting a highly nonlinear fibre-based thresholder and by careful system engineering.
