摘要
随着4G建设的深入,分布式基站的建设比例正不断提高,传送网寻求新的变革。首先分析了回传网络层面所面临的容量压力,建议直接提升接入环速率以满足承载更多拉远站的容量需求;接着,分析了前传网络层面所面临的纤芯压力,建议采用Bi Di光模块以及光纤扩容两种思路减少纤芯占用;最后,探讨了以拉远站作为整合前/回传网络两个层面,进一步优化传送网结构的可能性。
With the development of the construction of 4G, the proportion of distributed base stations is constantly improving and transport network is demanding some new changes. First of all, this paper analyzes backhaul network level facing capacity pressure and suggests the way to enhance access ring rate directly to meet the capacity requirements from more remote stations. Then, it analyzes fronthaul network level facing fiber cores pressure and suggests using Bi Di optical module and optical fiber expansion device to reduce fiber cores occupied; Finally, it investigates the effect of remote stations on combing fronthaul backhaul network levels and the probability of optimizing the structure of transport network further.
