摘要
BBU池组化成为无线网络发展的重要趋势,移动前传应用成为BBU池组化中的一个重要内容,如何解决拉远RRU的传输承载,业内提出了多种解决方案,包括光纤直驱、无源彩光、有源WDM/OTN和G.metro等方案。详细介绍了BBU池组化后移动前传网络的应用需求,在此基础上重点分析比较了不同的传输解决方案,最后给出了BBU池组化部署过程中移动前传网络的不同应用场景传输解决方案。
BBU pooling is the development trend of wireless access technique and mobile fronthaul becomes an important issue during the BBU pooling development. How to transport the signal from RRU to BBU pool, different solutions are proposed, including dedicated fibers, passive CWDM, active WDM/QTN, G.metro, and so on. The application requirements of mobile fronthaul in BBU pooling deployment is introduced, based on which, the different solutions are analyzed and compared, and finally the so- lutions on different application scenarios of mobile fronthaul are suggested.
