      数据中心“三超”光互联内部是相互联系,相互促进的。
超大容量的实现需要解决信号间串扰和传输中损耗的问题,而                                             [13]Masuda A,Yamamoto S,Taniguchi H,et al.255-Gbps PAM-
解决这类问题一般使用先进的DSP算法,但传统的DSP算法复杂                                    8 transmission under 20-GHz bandwidth limitation using NL-MLSE

能力。然而,高性能的DSP算法往往需要专用的硬件,这会增加
系统硬件成本,所以更低损耗的器件被研制以实现数据中心低                                             [14]Taniguchi H,Yamamoto S,Kisaka Y,et al.800-Gbps PAM-
