Abstract:A novel subcarrier multiplexing based carrier sense technique called SCM-CS is proposed and is experimentally demonstrated. It can prevent the contention in optical frequency division multiple access networks that use an access protocol based on a fixed-wavelength transmitter and wavelength-tunable receiver. When two or more SCM signals on the same subcarrier frequency at different wavelengths simultaneously address the same destination node, SCM-CS detects the sum of the subcarrier frequencies by using RF het… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
