Bidirectional WDM PON Enabled by Reflective ONUs and a Novel Overlapped-Subcarrier Multiplexing Technique
Bidirectional WDM PON Enabled Reflective ONUs Novel Overlapped-Subcarrier Multiplexing Technique
2011/5/20
A symmetric WDM-PON architecture using an innovative overlapped-SCM scheme that maximizes the spectrum usage of a bandwidth-limited RSOA is demonstrated. Error-free operation is achieved using realist...
A Novel Multicast Overlay Scheme for WDM Passive Optical Networks using Optical Carrier Suppression Technique
WDM Passive Optical Networks Optical Carrier Suppression Technique
2009/7/20
A WDM-PON with simultaneous delivery of 10-Gb/s downstream unicast and upstream data as well as 10-Gb/s multicast data is proposed. Downstream multicast data is superimposed onto the subcarrier genera...
