Abstract

A novel wired and wireless hybrid access system based on self-homodyne and heterodyne technology is presented in this paper. With the 16 Quadrature Amplitude Modulation(16QAM) and optimized self-homodyne mechanism, the system achieves 224Gbit/s wired access. Through optical heterodyne technology, the 30GHz wireless covering is implemented. The performance of the system is further improved by using the Pre-Compensation module and Post-Compensation module. Self-homodyne system improves the Optical Signal Noise Ratio(OSNR) threshold by 1.7 dB compared to the conventional coherent system, while reducing the system device requirements. The adoption of the Pre-Compensation module will save 1.7dB of OSNR tolerance even further. DSP modules of low computational complexity suitable for self-homodyne system and heterodyne system are redesigned.
