Overlay of Multicast Service in WDM-PON Based on Dynamic Wavelength Reflection Scheme
Résumé
We propose a novel scheme to overlay multicast service over a wavelength-division-multiplexed (WDM) passive optical network (PON) based on dynamic wavelength reflection scheme. At the optical line terminal (OLT), for each WDM channel, a dynamic wavelength reflector is used to selectively bypass the corresponding optical carrier to avoid multicast data superimposition, while the remaining optical carriers go through the dynamic wavelength reflector and simultaneously carry the multicast data. The proposed scheme is experimentally demonstrated with 5-Gb/s downstream unicast, multicast data and 625-Mb/s upstream re-modulated data.
