First Demonstration of Interrupt-Free Whisper Ranging for In-Service ONU Activation in TDM-PON Running Low-Latency Services
04 September 2018
We propose and validate an upstream-traffic-disruption-free ONU activation method enabling low-latency services over TDM-PON. We demonstrate ranging using 5-&μs-long empty window independent of the fiber length; an improvement over 250/450-&μs quiet windows in conventional ranging for 20/40-km differential fiber distance.
