摘要
对DP-QPSK(偏振复用正交相移键控)调制和相干接收技术在低速系统中的应用进行了研究, 实现了2.67 Gbit/s速率的实时传输。实验结果表明, DP-QPSK调制和相干接收技术对无中继ULH(超长跨距)光传输系统的OSNR(光信噪比)容限有优化作用。
Abstract
This paper studies the applications of DP-QPSK modulation and the coherent reception technology in low-rate systems and realizes 2.67 Gbit/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.
