Abstract

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.
