Optimizing Bandwidth Allocation in GPON as a Backhaul to Fulfill 5G Latency Requirement

Abstract

To achieve full deployment of 5G services, a backhaul network solution is required to connect the central office to the BTS (Base Station). Some of the current alternatives used for backhaul solutions implement Wireless technology (Radio IP) and wire-line (copper and fiber). The use of fiber network can be used with Metro Ethernet or GPON network approach. The focus of GPON is based on the problems encountered when the requirement of latency is fixed at below 5 ms. Based on the findings of this research, in order to meet the 5G latency requirement of 5ms, the most suitable capacity allocation is 70% with average latency combined of upstream and downlink is 2.8ms. Furthermore, the average optimum bandwidth capacity is 72.10 % and 72.59 % for GPON and XGSPON respectively
