摘要

5G前传网络架构发生重大变化，C-RAN有望成为5G前传网络的主流组网方式。结合5G前传网络的新需求，在分析光纤直驱、无源WDM、有源WDM/OTN等现有方案的基础上，提出了面向5G前传网络的开放式波分复用（open-WDM）系统。该系统采用波分复用技术，缓解光纤资源压力；基于半有源架构，部署灵活；采用低成本管控技术，保障前传网络的可管可控和高效运维。

Abstract

C-RAN may be a promising way for 5G fronthaul network associated with significant changes in 5G fronthaul architecture.Based on the analysis of existing schemes such as optical fiber direct connection

passive WDM and active WDM/OTN

open wavelength division multiplexing (open-WDM) system was proposed to satisfy the new requirements of 5G fronthaul network.In the open-WDM system

WDM technology is used to save optical fiber resource and the semi-active architecture can achieve flexible deployment.The low-cost management and control technology was further applied to perform efficiently network operation.
