Abstract: A fiber optic cassette includes a housing with a base and a cover. The base defines an open front between first and second sidewalls, which transition into first and second curved rear wall portions. The first and second curved rear wall portions define an adapter mount therebetween forming at least one pocket. A signal entry location defined by at least one MPO adapter is positioned within the pocket and defines an exterior port and an interior port. A fiber optic cable connectorized by an MPO format connector is mated to the exterior port. An adapter block defining a plurality of second fiber optic adapters is mounted to the base via a first snap-fit interlock to close the open front, each second fiber optic adapter including an exterior port and an interior port.

Abstract: An essentially nickel- and rhenium-free catalyst is described comprising ruthenium on a titania support where the titania is greater than 75% rutile. A catalytic system containing a nickel-free catalyst comprising ruthenium on a titania support where the titania is greater than 75% rutile, and a method using this catalyst in the hydrogenation of an organic compound in the aqueous phase is also described.
