随着全球宽带业务的增长,100G传输网和相关设备已规模化商用,400G的标准化进程也已正式开启。但从互联网业务与网络流量发展趋势来看,400G仍然不能满足未来带宽持续增长的需求,以太网速率进一步演进到T比特量级已成业界共识,基于超级信道的T比特大容量光传输技术成为当前研究的热点和难点。 With the growth of global broadband services, 100G transmission networks and related equipment have been commercialized on a large scale and the standardization of 400G has also been officially launched. However, from the perspective of the trend of Internet traffic and network traffic, the 400G still can not meet the demand for continued bandwidth growth in the future. The further development of the Ethernet rate to the T-bit level has become the consensus of the industry. The T-channel high-capacity optical transmission technology based on the super channel becomes The current research hot and difficult.
