摘要

随着5G网络流量快速增长，6通道25 Gbit/s前传承载需求日趋明显。介绍了移动前传在现网部署的主要方案和标准化情况，针对6通道25 Gbit/s前传低成本承载需求，提出了一种基于CWDM/光环行器的承载方案，分析了该方案的优势与面临的挑战，介绍了该方案在实验室测试和现网试点的情况。

Abstract

With the rapid growth of 5G network traffic

the bearer requirement for 6-channel 25 Gbit/s fronthaul has become increasingly obvious.The main schemes and standardizations of fronthaul technology in the existing network were introduced.A novel bearer scheme based on CWDM and optical circulator to satisfy the requirements for 6-channel 25 Gbit/s fronthaul with low cost was proposed.The advantages and challenges of the scheme were analyzed.Tests in laboratory and pilots in actual network were introduced.
