Demonstration of ONU Activation for In-Service TDM-PON Allowing Uninterrupted Low-Latency Transport Links

We propose an upstream-traffic-disruption-free ONU activation method enabling low-latency services over TDM-PON. We demonstrate ranging using only 5-μs-long empty window independent from fiber length, a significant improvement over 250/450-μs quiet windows required in conventional ranging.
