Abstract :
We demonstrate single-channel 960-Gbit/s, 64 QAM-150 km transmission using the orthogonal TDM of coherent Nyquist pulses. Coherent mixing between optical Nyquist data and LO pulses enables demultiplexing and homodyne detection with a high SNR. The spectral efficiency reaches 10.0 bit/s/Hz.
