Abstract

We present here the work performed in the EU-funded flexible optical cross-connect (FOX-C) project, which investigates and develops new flexible optical switching solutions with ultra-fine spectral granularity. Thanks to high spectral resolution filtering elements, the sub-channel content can be dropped from or added to a super-channel, offering high flexibility to optical transport networks through the fine adaptability of the network resources to the traffic demands. For the first time, the FOX-C solutions developed in the project are investigated here and evaluated experimentally. Their efficiency is demonstrated over two high spectral efficiency modulation schemes, namely multi-band orthogonal frequency division multiplexing (MB-OFDM) and Nyquist WDM (N-WDM) formats. Finally, in order to demonstrate the relevance of the FOX-C node concepts, a networking study comparing the economic advantages of the FOX-C optical aggregation solution versus the electronic one is performed.

高比特率弹性光子传输网络的柔性光交叉连接[特邀]

本文介绍了欧盟资助的柔性光交叉连接(FOX-C)项目所做的工作，该项目研究和开发了具有超细光谱粒度的新型柔性光交换解决方案。由于采用高光谱分辨率滤波元件，子信道内容可以从超级信道中删除或添加到超级信道中，通过网络资源对业务需求的良好适应性，为光传输网络提供了高度的灵活性。本文首次对项目中开发的FOX-C解决方案进行了研究和实验评估。通过两种高频谱效率的调制方案，即多频带正交频分复用(MB-OFDM)和奈奎斯特WDM (N-WDM)格式，证明了它们的效率。最后，为了证明FOX-C节点概念的相关性，进行了一项网络研究，比较FOX-C光聚合解决方案与电子聚合解决方案的经济优势。
