Multiband Carrierless Amplitude Phase Modulation for High Capacity Optical Data Links
Miguel Iglesias Olmedo,Tianjian Zuo,Jesper Bevensee Jensen,Qiwen Zhong,Xiaogeng Xu,Sergei Popov,Idelfonso Tafur Monroy +6 more
TL;DR: In this paper, the authors proposed the use of carrierless amplitude phase (CAP) in a novel multiband approach (MultiCAP) that achieves record spectral efficiency, increases tolerance towards dispersion and bandwidth limitations, and reduces the complexity of the transceiver.
Journal ArticleDOI
Advanced modulation formats for 400-Gbps short-reach optical inter-connection
Xiaogeng Xu,Enbo Zhou,Gordon Ning Liu,Tianjian Zuo,Qiwen Zhong,Liang Zhang,Yuan Bao,Xuebing Zhang,Jianping Li,Zhaohui Li +9 more
TL;DR: Different advanced modulation formats and components suitable for SR-ONs, the impairments induced by all kinds of defects and bandwidth limitation of opto-electronic components and the corresponding compensation techniques based on DSP algorithms have been discussed and demonstrated.
Proceedings ArticleDOI
