The airflow ducting arrangement accommodating thermal cooling of active equipment having internal side-to-side air cooling arrangements.

Abstract: A DSX system having a plurality of jacks mounted in a chassis, the jacks including IN and OUT ports accessible from the front of the chassis and tip and ring springs corresponding to each of the IN and OUT ports. The chassis also includes IN and OUT co-axial cable connectors electrically connected to the tip and ring springs of the jacks, and MONITOR co-axial cable connectors for use in monitoring signals transmitted through the IN and OUT connectors.

Abstract: A splice tray arrangement including a tray and a splice chip arrangement. The splice chip arrangement including stackable splice chips defining channels for holding splice elements. Each of the splice chips including a mounting arrangement for mounting the splice chip at a mounting location on the tray, and a stacking arrangement for mounting the splice chip upon another splice chip.

Abstract: A fiber optic connector and a fiber optic adapter are disclosed that are manually connectable and disconnectable with each other by a slideable latching means. The fiber optic connector includes an end defining a plug portion. The plug portion holds a ferrule and also directly engages a port on the fiber optic adapter. The plug portion includes a protrusion which also forms a latch catch. The port of the fiber optic adapter includes a flexible retention latch within a slot. The slot engages the protrusion and thus rotationally aligns the fiber optic connector and adapter. The flexible retention latch snaps into and out of the latch catch when the plug portion of the fiber optic connector is slid into and out of the port of the fiber optic adapter thus providing the slideable latching means. Angled retaining surfaces are provided on the retention latch and the latch catch that engage each other. Angles defining the angled retaining surfaces are chosen to provide desired holding and release characteristics.

Abstract: A cable management assembly, and methods related thereto, including a panel having a plurality of discrete openings, including first shaped apertures and second shaped apertures. The assembly further including cable management devices having low-profile mounting arrangements. The low-profile mounting arrangements being configured to mount the cable management devices at selected locations on the panel.

Abstract: A fiber distribution hub (FDH) provides an interface between an incoming fiber and a plurality of outgoing fibers. The FDH includes a cabinet, at least one door pivotably mounted to the cabinet, and a frame pivotably mounted within the cabinet. The doors wrap around the sides and the front of the cabinet to provide access to both the front and sides of the frame when the doors are open. The frame can pivot out of the cabinet through the open doors to enable access to the rear of the cabinet and the rear side of the frame. The frame includes a termination region and a splitter region. The frame can include a storage region and/or a pass-through region.

Abstract: A cable radius limiter having a radius limiting surface that prevents damage to cables due to excessive bending. The cable radius limiter includes mounting structure and cable retaining structure arranged such that the limiter can be operably oriented and mounted to a planar mounting surface in a number of mounting orientations.

Abstract: A splitter unit including a chassis containing splitter cards. The splitter unit includes a central processing unit mounting location. The splitter unit also includes test access devices that are inactive when the central processing unit mounting location is vacant. The splitter unit is configured such that the splitter cards provide passive signal splitting even when the central processing unit mounting location is vacant.
