Optimized Routing and Spectrum Assignment for Video Communication over an Elastic Optical Network [PDF]
Elastic optical network (EON) efficiently utilize spectral resources for optical fiber communication by allocating the minimum necessary bandwidth to client demands. On the other hand, network traffic has been continuously increasing due to the wide penetration of video streaming services, so the efficient and cost-effective use of available bandwidth ...

在分析偏振模色散(PMD)引起传输信号去偏振导致偏振分光光信噪比(OSNR)监测方法测量误差问题的基础上,提出一种用扰偏振器和偏振分束器来克服PMD影响,实现OSNR精确监测的方案。波分复用传输信号经扰偏振器扰偏后解复用分离出待测信道信号,偏振分束器将待测信号分成偏振正交的两个支路信号,然后通过检测到的两支路信号功率之间的关系来得到信道的OSNR。仿真实验证实了新方法对PMD影响不敏感。
