摘　　要：为了提高PM-CO-OFDM-PON系统中上行数据的传输速率,提出采用偏振复用结构与相干检测技术相结合,通过光载波源方式实现上行链路光网络单元无色化传输的技术方案.利用光学软件VPI和Matlab,搭建了基于偏振复用技术的40Gb/s PM-CO-OFDM-PON系统仿真平台,结果表明:该方案可有效提高PM-CO-OFDM-PON系统中上行数据传输速率,并实现光网络单元无色化;利用相干检测比直接检测可以更高地提高接收端的灵敏度.A polarization multiplexing scheme for polarization division multiplexing orthogonal frequency division multiple with coherent detected-based passive optical networks was proposed, in which polarization multiplexing was used at the Optical Network Unit（ONU） for the upstream transmission to increase the transmission data rates and double the spectral efficiency. ONU colorless was realized by optical carrier way. VPI and MATLAB were used for the PM-CO-OFDM-PON simulation platform. The results show that the proposed PM-CO-OFDM-PON architecture is scalable, improves the data rates in the upstream of PM-CO-OFDM-PON, and ONU colorless is realized effectively. Moreover, with coherent detected,the receiver sensitivty is improved.
