Many CSPs are concerned about network monetization.  Many wireless CSPs are experiencing strong ROI but the costs of mobile backhaul are becoming a concern given the large increases in data traffic from 3G/4G/LTE.  Growth in connected devices, bandwidth demand and video-intensive applications continues. This growth impacts QoE (quality of experience) for all users.  Many PON component and equipment vendors are facing declining revenues as ASPs continue to drop and as volumes shift from OLT ports to ONTs/ONUs devices. Introduction – PON has potential beyond FTTH  PON supports different types of users running different types of applications with different bandwidth, latency and jitter requirements:
