Field experiments of 42.7 / 128.1 Gb/s WDM-OTDM transmultiplexing and all-optical dual-wavelength regeneration at the OTDM rate are presented. By using the asynchronous retiming scheme, we achieve error-free buffer-less data grooming with time-slot interchange (TSI) capability for OTDM meshed networking. We demonstrate excellent performance from the system, discuss scalability, applicability, and the potential reach of the asynchronous retiming scheme for transparent OTDMdomain interconnection.
We demonstrate a regenerative optical grooming switch for interconnecting 130 Gbit/s and 40 Gbit/s networks with switching functionality in time, space and wavelength domain. Q-factors are above 21 dB.
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.
