Transmission of 44-Gb/s Coherent Optical OFDM Signal with Trellis-Coded 32-QAM Subcarrier Modulation
21 March 2010
: We experimentally demonstrate the transmission of a spectrally-efficient 44-Gb/s CO-OFDM signal whose subcarriers are trellis-coded with 32-QAM over a 990-km dispersion-managed SSMF link, and show the performance improvements obtained through the coded-modulation and self-phase-modulation compensation.
