A Flexible Low-Latency Metro-Access Converged Network Approach Based on Time-Synchronized TWDM-PON

A flexible time-synchronized TWDM-PON (TS-TWDM-PON) architecture is proposed and implemented for low-latency metro-access communication. Results show that a two-order-of-magnitude reduction in end-to-end delay can be achieved with the new TS-TWDM-PON architecture.
