摘要
随着4G网络的部署,前传网络的光纤资源消耗过多的问题愈加凸显。传统通过无源波分设备WDM和CPRI压缩技术虽然在一定程度上解决了传输资源问题,但是面向5G通信,为了满足高带宽、低时延、协作绿色节能化和无线云化等要求,这就需要传输网络架构也随之调整。通过对传统基于CPRI承载方案研究和各承载方案的性能指标对比分析,并结合现有设备的能力要求,提出了一种新的能满足前传需求的承载方案,进一步提升传输网络中的光纤利用率。
With the deployment of 4G networks, fronthaul network optical fiber resource consumption is more and more serious. The traditional WDM and CPRI compression technology, which is based on the passive wave device, can solve the problem of transmission resources to a certain extent. However, in order to meet high-bandwidth requirements, low latency, collaborative green energy saving and wireless cloud in 5G communications, the transmission network architecture needs corresponding adjustment. Compared CPRI based bearing solution with other bearing solutions in performance metrics, a novel bearing solution to meet fronthaul requirements was presented according to the capability of the existing devices, which can further improve the utilization in optical fi ber transmission networks.
