Implementation of 64QAM at 42.66 GBaud using 1.5 Sample per Symbol DAC and demonstration of up to 300 km fiber transmission
09 March 2014
We demonstrate 400 Gb/s data generation using 64QAM at 42.66 GBaud and at a reduced oversampling ratio of 1.5 sample per symbol including digital Nyqist filtering and spectral equalization. Even at 24% FEC overhead successful transmission over 300km ULAF has been shown.
