摘要

We propose and experimentally demonstrate a simplified coherent receiver based on heterodyne detection with only two balanced photodetectors and two analog-to-digital converters. The polarization diversity hybrid can be simplified relative to the conventional one. The detected intermediate frequency signals are first downconverted to baseband with inphase and quadrature separation. Using this scheme, we successfully demonstrated the eight-channel 50 Gb /s polarization division multiplexed quadrature phase shift keying WDM signal with heterodyne detection based on digital signal processing over 1040 km single-mode fiber 28 with erbium-doped fiber amplifier only amplification.
