摘要
随着4G网络和应用的快速发展,分布式基站逐渐增多,出现了BBU与RRU间移动前传光网络的迫切需求。介绍了3种新型的移动前传方案,基于波分复用的移动前传/CPRI承载方案、基于G.metro的移动前传/CPRI承载方案、基于DMT技术的低成本高速移动前传/CPRI承载方案。
With the rapid development of 4G networks and applications, distributed base stations keep increasing and the demand for fronthaul networks between BBU and RRU becomes stringent and urgent. Three novel optical solutions for mobile fronthaul will be introduced and discussed, including WDM based solution, G.metro-based solution and low-cost high bit rate with low-class transceiver solution.
