First time, an unprecedented 42dB loss budget was realized by using hybrid DWDM-CDM (Code Division Multiplexing)-PON without optical amplifier. We experimentally demonstrated 100km 16λ-DWDM-CDM-PON bidirectional transmission with 62.5Mbps x 32 users / λ symmetry guaranteed bandwidth. Long reach PON is expected to reduce CapEx and OpEx cost.
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.
