Low Latency DBA Scheme for 5G Mobile Service in Multilane-Based 50G-EPON

We present the cyclic-based low latency DBA using grant fragmentation technique to satisfy the latency and bandwidth requirements of 5G mobile services in 50G-EPON. It can achieve the maximum latency of 326-µs and throughput of 20-Gb/s in gold class service even if traffic load increases.
