AbstractIn this study, two schemes of optical power splitter nodes to enable direct local intercommunications between optical network units (ONUs) in a passive optical network (PON) are proposed and analyzed. In comparison with the existing schemes, the new schemes dramatically increase the number of ONUs supported in a PON with the capability of direct local communication. Experimental demonstrations confirm that our proposed schemes can fit into gigabit PON standard by meeting its requirement on the power penalty. © 2009 Wiley Periodicals, Inc.
