Research on the Application of Novel Optical Fiber in Backbone Network

骨干网正向大容量、长距离、低功耗演进。相比于普通单模光纤,新型光纤可以有效提升无电中继传输距离,有助于推动光电混合交叉技术、400 Gbit/s相干波分技术等关键技术在骨干网中的应用。首先介绍了光纤网络的现状,随后阐述了光纤的发展历程和传输特性,并比较了不同光纤的性能指标,最后分析了新型光纤在骨干网中的应用场景。

Optical backbone network are evolving to large capacity,long distance and low power consumption. Compared with standard single-mode fiber,novel optical fiber can increase transmission distance efficiently without electric relay,which helps to promote the application of hybrid wavelength/sub-wavelength cross connect and 400 Gbit/s coherent wavelength division multiplexing for backbone network. First,the background of the optical fiber network is introduced. The developing process and transmission characteristic of optical fiber is subsequently described. The performance of several optical fibers are also analyzed. Finally,the application scenarios of novel optical fibers for backbone network are discussed.
