5 x 50 Gb/s WDM Transmission of 32 Gbaud DP-3-PSK over 36.000 km Fiber with Spatially Coupled LDPC coding
09 March 2014
A novel 3-PSK modulation format with 2 dB SNR gain according to information theory over BPSK has been implemented for ultra long haul transmission. Supported by 95% FEC overhead and spatially coupled LDPC coding pre-FEC symbol error rates up 0.2 are feasible leading to 50% reach extension to 36.000 km transmission distance.
