PM-QPSK相干系统中改进的OSNR监测方法

Guangtongxin yanjiu, 2014
针对100Gbit/s及以上PM-QPSK（偏振复用正交相移键控）相干光通信系统,提出了一种改进的基于统计矩的带内OSNR（光信噪比）监测方案,并在搭建的100Gbit/s PM-QPSK相干接收系统中对该方案进行了数值仿真。结果表明,在525dB的OSNR范围内,该改进方案对不同占空比的RZ（归零）码调制信号的监测误差均小于0.5dB;根据商用相干接收机对接收端OSNR的要求,取其参考值为14dB,则在0.5dB的监测范围内,对CD（色散）的容忍度为2 400ps/nm,对一阶PMD（偏振模色散 ...

Static and Dynamic Routing, Fiber, Modulation Format, and Spectrum Allocation in Hybrid ULL Fiber-SSMF Elastic Optical Networks [PDF]

arXiv
Traditional standard single-mode fibers (SSMF) are unable to satisfy the future long-distance and high-speed optical channel transmission requirement due to their relatively large signal losses. To address this issue, the ultra-low loss and large effective area (ULL) fibers are successfully manufactured and expected to deployed in the existing optical ...
