Abstract: Port occupancy detection for connector panels is provided. In one embodiment, a connector panel comprises: a communications unit communicatively coupled to a network; and at least one modular port adapter assembly comprising: a plurality of communications couplers; and a plurality of port occupancy sensors each coupled to a sensor circuit. Each of the port occupancy sensors are configured to sense when the couplers are occupied. The panel communications unit obtains from the sensor circuit which of the couplers are occupied. The panel communications unit communicates port occupancy information to a gateway indicating circuit which of the couplers are occupied. A chassis including sidewalls extends between a front and a rear to define an interior, and including guides on the sidewalls. A plurality of blades mounted to the guides of the chassis, each blade including a midplane bus assembly configured to communicatively couple the sensor circuit to the panel communication unit.

Abstract: A cable assembly for optical monitoring is assembled by laying optical fibers into an adhesive layer on a substrate to form an optical circuit. First ends of the fibers are arranged in various groups and second ends of the fibers are arranged in various groups. Groups at a first end of the circuit are spliced to coupler input fibers and coupler output fibers. Groups at the second end of the circuit are terminated at one or more input connectors, one or more output connectors, and one or more monitoring connectors. Some cable assemblies monitor signals received at the input connectors. Other cable assemblies monitor signals received at both the input connectors and the output connectors.

Abstract: An adapter assembly includes a single-piece or two-piece multi-fiber adapter defining a recess at which a contact assembly is disposed. The adapter assemblies can be disposed within adapter block assemblies or cassettes, which can be mounted to moveable trays. Both ports of the adapters disposed within adapter block assemblies are accessible. Only one port of each adapter disposed within the cassettes are accessible. Circuit boards can be mounted within the block assemblies or cassettes to provide communication between the contact assemblies and a data network.

Abstract: An adapter block assembly includes two housing pieces that cooperate to hold one or more adapters therebetween. The two housing pieces are removably latched together. Labels can be placed over the latches. Certain types of adapter block assemblies are configured to receive multi-fiber plug connectors. Certain types of adapter block assemblies include securement arrangements at opposite ends thereof to aid in mounting the adapter block assemblies to frames, trays, chassis, or other such structures.

Abstract: A fiber optic telecommunications device includes a rack for mounting a plurality of chassis, each chassis including a plurality of trays slidably mounted thereon and arranged in a vertically stacked arrangement.

Abstract: A fanout arrangement includes a fanout body; a mesh sleeve; and an arrangement to hold the mesh sleeve to the fanout body. The fanout body may have one or more removable sheath organizers to retain the upjacketing for the fanned out optical fibers.

Abstract: A fiber optic telecommunications device includes a frame and a fiber optic module including a rack mount portion, a center portion, and a main housing portion. The rack mount portion is stationarily coupled to the frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction. The main housing portion of the fiber optic module includes fiber optic connection locations for connecting cables to be routed through the frame. The center portion of the fiber optic module includes a radius limiter for guiding cables between the main housing portion and the frame, the center portion also including a latch for unlatching the center portion for slidable movement. Slidable movement of the center portion with respect to the rack mount portion moves the main housing portion with respect to the frame along the sliding direction.

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.
