近日,武汉邮电科学研究院研制成功,可以实现一根光纤上67.5亿对人(135亿人)同时通话。这是在我国首次实现560Tb/s超大容量波分复用及空分复用的光传输系统实验,也标志着我国在“超大容量、超长距离、超高速率”光通信系统研究领域迈上了新的台阶。随着移动互联网、云计算、大数据、物联网应用的快速兴起,流量激增给信息通信网络带
Recently, Wuhan Institute of Posts and Telecommunications successfully developed, you can achieve a fiber on the 6.75 billion pairs of people (13.5 billion people) at the same time call. This is the first optical transmission system experiment in our country to realize 560Tb / s large capacity WDM and space division multiplexing, and also marks China’s research field of “ultra-large capacity, ultra-long distance and ultra-high speed” optical communication systems To a new level. With the rapid rise of mobile internet, cloud computing, big data and internet of things applications, the traffic surges to the information and communication network
