Abstract: A jack receptacle for a plug connector is configured with a receptacle profile having one or more keying features disposed on a removable bezel which correspond to complementary keying features formed on a plug connector. The jack receptacle with removable keyed bezel can be configured to allow only plug connectors with the corresponding keying features to mate therewith, while preventing plugs without the corresponding keying features from mating. These features can prevent non-certified devices from being plugged into a power-delivering data circuit, and also permit the keying of receptacles with removable bezels based on ratings for transmission of different power levels. Other embodiments of the keyed jack receptacle can be configured to allow both plug connectors with the corresponding keying features and plug connectors without the corresponding keying features from mating therewith. This provides a means to migrate specific circuits within the system to limited power usage.

Abstract: A fiber optic cassette includes structural features that maintain segregation between incoming and outgoing optical fibers. A dividing wall and a set of splice holders within the cassette together define two separate chambers within the cassette. Cable entry openings on the rear end of the cassette are configured to receive fiber optic cables into the rear chamber defined by the dividing wall and the splice holders. The front chamber is configured to hold patching fibers that interface with fiber optic adapters on the front of the cassette. The patching fibers and incoming optical fibers can be spliced as needed, and the splices held in place by the splice holders. This arrangement ensures that the incoming optical fibers from the fiber optic cable and the patching fibers remain segregated, such that the splice points are the only points of contact between the two sets of fibers.
