Cao Li, Song Xinming, Huang Liyan, et al. Research on applications of coherent reception technology in low-rate ULH systems[J]. 2015,(1):9-10. DOI: 10.13756/j.gtxyj.2015.01.003.
This paper studies the applications of DP-QPSK modulation and the coherent reception technology in low-rate systems and realizes 2.67Gbit/s real-time transmission.Experimental results show that DP-QPSK modulation and coherent reception technology can optimize the OSNR tolerance for Ultra-Long Haul(ULH)optical transmission systems.
