随着接入网的快速发展,各种无源光网络应用技术日渐大成熟。文章介绍了几种应用于无源光接入网中的新型混合调制方式,并对这些混合调制方式的关键技术进行了阐述、分析、比较和总结,以期为未来研究提供参考。
As the development of the access network, PON technologies make a great progress. In this paper, we explore and compare the applications of several combined modulation formats in the passive optical network (PON), validating the great potential of using the combined modulation scheme in future access networks.
