Bladed chassis systems and removable cassettes

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. An MPO format connector is mated to the interior port of the MPO format adapter and terminates a plurality of fibers that are terminated at opposite ends with connectors that are mated to the interior ports of the second fiber optic adapters, wherein each fiber extending from the adapter mount to the second fiber optic adapters being the same length and relaying the fiber optic signal to fiber optic connectors to be coupled to the exterior ports of the adapters of the adapter block.
