Multipoint-to-point data aggregation using a single receiver and frequency-multiplexed intensity-modulated ONUs
We demonstrate 2.5-GHz-spacing frequency multiplexing capable of aggregating 64 intensity-modulated end-users using low-speed electronic and optoelectronic components. All optical network units (ONUs) achieved high per-user capacity with dedicated optical bands, enabling future large-bandwidth and low latency applications.
