| Popis: | To meet the latency and bandwidth requirements of 5G mobile services and next-generation residential/business services, we present high speed and low-latency passive optical network (PON) enabled by time controlled-tactile optical access (TIC-TOC) technology. The TIC-TOC technology could support bandwidth-intensive as well as low-latency services for 5G mobile network by using channel bonding and low-latency oriented dynamic bandwidth allocation (DBA). In order to confirm the technical feasibility of TIC-TOC, FPGA-based OLT and multi-speed ONU prototypes are implemented. We experimentally demonstrate the real-time packet transmission up to 50 Gb/s without packet loss during 48-hour through the channel bonding in a single optical distribution network (ODN) with 20 km reach and 1:64 split ratio. Less than 400 μs latency for 5G mobile services is also demonstrated. Furthermore, we confirm that total throughput could be expanded up to 100 Gb/s by adding more channels. |
