摘要
为适应各种新兴业务对带宽的迫切需求,在光纤通信系统中必须采用新的复用维度来实现信道容量的有效增长。从确保多芯-少模光纤(MC-FMF)性能的角度,讨论了MC-FMF的纤芯折射率分布、纤芯排列和光纤性能;基于MC-FMF系统使用的关键光器件,阐述了MC-FMF传输系统的组成和工作原理。通过介绍在MC-FMF上实现10.16Pb/s的传输实验,证实了MC-FMF是实现超大容量传输的有效方法之一。
In order to meet the urgent demand of bandwidth for various emerging services, it is necessary to adopt new multiplexing dimension in optical fiber communication system to realize the effective increase of channel capacity. This letter from the application angle of the multicore-few modes fibers（MC-FMF）, the index profiles and the arranges of the core and the properties of the MC-FMF is explored; from the key optical components used of MC-FMF the transmission system configuration and the system working theory of MC-FMF are proposed. At last, 10.16 Pb/s transmission experiments is cited over MC-FMF. The transmission experiments is shown that MC-FMF is the one of effective methods of the ultra larger transmission.
