【 摘 要 】

References(10)Quadrature amplitude modulation (QAM) is an excellent modulation format for realizing optical communication systems with a high spectral efficiency aiming at 10bit/s/Hz. We describe a three-channel frequency division multiplexed (FDM) and polarization-multiplexed 1 Gsymbol/s, 64 QAM coherent transmission over a 160km SMF with a 1.4GHz spacing. The total capacity for each channel reaches 36Gbit/s in an optical bandwidth of 4.2GHz, resulting in a spectral efficiency of 8.6bit/s/Hz.
