Abstract:A front-connection technique using the front-side of the circuit board in rack systems configured like bookshelves is proposed to increase pin-counts for high-through-put switching modules (>20 Gb/s). This configuration technique was implemented using newly developed front connectors and flexible printed-circuit (FPC) cables that are both impedance-matched. This configuration enables the use of a new transmission route that meanders through every signal transmission line of every circuit board, backplane, and … 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.
