100 Gb/s高灵敏度相干光通信装置
100 Gb/s High Sensitivity Coherent Optical Communication System
摘要
设计了一种采用内差接收,数字信号处理电域均衡技术,偏振复用四相移键控调制码型的高灵敏度相干光实时通信装置。该装置线路传输比特率为127 Gb/s,传输净荷为99.53 Gb/s,在背靠背条件下获得了-38.2 dBm的接收灵敏度,实现了高灵敏度高速率实时数据传输。该装置主要采用商用化光电器件,设计符合国际电信联盟的建议,具有较好的应用前景。
Abstract
A digital signal processing, infradyne, polarization multiplex quartered phase-shift keying ultra high sensitivity coherent optical communication system is reported in this paper. The transmission bit-rate is 127 Gb/s and the payload bit-rate is 99.53 Gb/s. Sensitivity of -38.2 dBm is achieved in real-time back to back transmission. In this system, commercial devices are widely used and the design follows ITU-T recommendation. Therefore, the system has great prospects of application.
