Hitless Dynamic Wavelength Allocation in Coherent WDM-PONs
Optical Fiber Communication Conference, 2016 We introduce a novel algorithm for real-time ONU activation (¿ - assignment) and reconfiguration (¿ - tuning) in WDM coherent PONs. The algorithm prevents service interruption of lighted channels and it is experimentally demonstrated by using real-time fully-analog coherent transceivers.
