摘要

We propose a 40Gbit/s star-16QAM(to define) system based on ISI(to define)-suppression technology and coherent detection. ISI-free BPSK optical signals generated by Mach-Zehnder modulators (MZM) and continuous wave (CW) lights are used to realize a star-16QAM signal. As a result, the obtained star-16QAM signal is also ISI-free. It turns out that the proposed ISI free star-16QAM has better performance in terms of eye opening and constellation diagram comparing with two conventional star-16QAM signals transmitted through 80-km standard single-mode fiber (SSMF) and detected by a coherent receiver.
