摘要

基于多波段的光传输系统被认为是有效提升光通信传输容量的方法之一，在C和L波段的基础上，利用其他波段进行传输可以充分挖掘现有光纤网络的传输潜力，解决大容量通信网络的瓶颈问题，其关键技术及系统的实现有利于推动相关技术的产业化进程，具有广阔的经济效益。文章对当前全波段光传输技术的研究现状进行了分析和探讨，重点对S、C和L波段的性能差异进行了实验分析研究，采用C和L波段常规器件，使用偏振复用16进制正交幅度调制（PDM-16QAM）格式完成了波长范围覆盖S、C和L，容量可达到122.4 Tbit/s的40 km光传输系统实验。验证了G.652.D光纤的多波段传输能力，为进一步研究多波段光传输技术提供了实验基础。

Abstract

The optical transmission system based on all-band is considered to be one of the methods to effectively improve the transmission capacity of optical communication. In addition of the C and L bands

the using of other bands for transmission can fully tap the transmission potential of the existing optical fiber network and solve the bottleneck problem of large capacity communication network. The realization of its key technologies and systems is conducive to promoting the industrialization process of related technologies

which has broad economic benefits. This paper analyzes and discusses the current research status of multi-band optical transmission technology. And then as the focus

the performance difference of S、C and L band is studied by experiments. Based on the devices designed for C and L bands

the experiment of 40 km transmission system covering on S、C and L band is completed by using Polarization Division Multiplexed 16 Quadrature Amplitude Modulation (PDM-16QAM) modulation format

and the transmission capacity can reach 122.4 Tbit/s. The multi-band transmission capability of G. 652.D optical fiber is verified

which provicles an experimental basis for further research on multi-band optical transmission technology.
