Capacity and Flexibility Improvement of Traffic Aggregation for Fixed 5G:Key Enabling Technologies,Challenges and Trends
文献摘要：
As the emergence of various high-bandwidth services and the requirements to support 5G/Wi-Fi 6 wireless networks,the next generation fixed networks,i.e.F5G,are expected to be real-ized in the 5G era.F5G is endowed with new char-acteristics,including ultra-high bandwidth,all-optical connections and optimal service experience.With the prospect of optical-to-everywhere,optical technolo-gies are used for mobile front-haul,mid-haul,and back-haul.Optical access networks would play an im-portant role in F5G to support radio access network and fixed access network.Low-latency PON is a key for cost effective-haul traffic aggregation.In terms of signal transmission,intensity modulation direct-detection(IM-DD)is a promising scheme due to its simple architecture.The fundamental challenge asso-ciated with direct-detection is the disappearance of the transmitted signal's phase.In access network,the flex-ibility and low latency are the two key factors affecting service experience.In this article,we review the evo-lution of PONs and the challenges of current PONs in detail.We analyze key enabling digital signal process-ing(DSP)techniques,including detection lineariza-tion for direct-detection and simplified coherent detec-tion,adaptive equalizers,digital filer enabled flexible access network and low-latency inter-ONU communi-cations.Finally,we discuss the developing trends of future optical access networks.
