A fiber distribution hub includes an enclosure defining an interior region and a frame body having a longitudinal axis. The frame body is rotatably mounted within the interior region of the enclosure such that the frame body can rotate about the longitudinal axis relative to the enclosure between a first terminal angular position and a second terminal angular position. The frame body is rotatably mounted within the interior region of the enclosure also such that the entire frame body remains within the interior region as the frame body rotates between the first terminal angular position and the second terminal angular position. The fiber distribution hub also includes a splitter coupled to the frame body and having a splitter input and a splitter output.

Certain types of aggregation enclosures include cable input ports and downwardly angled cable output ports. A cover is pivotally coupled to the body so that the cover moves between an open position and a closed position. A modular component panel may be disposed within the enclosure. The component panel includes one or more distribution components (e.g., fiber distribution components or power distribution components) configured to connect at least a portion of an incoming cable to at least a portion of an outgoing cable.

Apparatuses and methods for optical fiber loop relaxation are provided for telecommunications management apparatuses, such as fiber optic telecommunications trays. The apparatus includes a radius limiter block for routing fibers therearound, and a fiber loop management recess provided on a peripheral surface of the radius limiter block. The fiber loop management recess is configured to receive a fiber loop management device between the radius limiter block and the fibers routed around the radius limiter block.

Electrical grounding assemblies for electrically grounding cables in cable closures. A grounding unit of the grounding assembly can serve as a common ground connection to multiple cables. The grounding unit includes mounting features that allow it to be easily mounted and unmounted from a slotted base plate positioned within the cable closure.

A fiber optic cable distribution box has an interface compartment for interfacing a first set of fibers when routed inside the compartment, with a second set of fibers associated with a fiber optic cable that is routed to the box. A drum region is disposed beneath the interface compartment. The drum region includes a cylindrical wall for supporting a fiber optic cable wound about the wall. The drum region is formed so that the box can turn about the axis of the cylindrical wall when a cable is paid out from the drum region. The interface compartment and the drum region are constructed so that the first set of fibers inside the interface compartment, originate from an inside end portion of the cable wound on the drum region.

The box houses and holds a connection terminal (TC), coupling an end connector (CE) of a drop cable (CD) and an end plug (PE) of an optical cord (CO) of a user and with a base (10) having a front face (10a) including a jaw (20) at a first edge (11) that receives and holds the drop cable (CD), a pair of lateral claws (30) in the middle locking the connection terminal (TC), and a stop (18) at a second edge (12) with a middle window (18a) enabling the optical cord (CO) to pass through. The box also includes a cover (60) with a front wall (61), and end walls (62) with windows (62a) that surround a portion of the jaw (20) and the middle window (18a) of the stop (18), and longitudinal walls (63), that can be locked on the front face (10a) of the base (10).

The box has a cover (2) and a base (1) with internal supports (25) positioning the optical fibers of splitters circumferentially; a support (24a/24b) for an unbalanced optical splitter (242) and a support (24a/24b) for a balanced optical splitter (241); and a support (26) for a set (23) of optical adapters for connectors (230) of optical cables, comprising an adapter for an optical signal input, an adapter for re-distributing the optical signal, and adapters for feeding the optical signal to a consumer unit, in which the unbalanced splitter (242) is fed by the optical signal input connector generating: an optical signal of greater power, feeding the optical signal redistribution connector; an optical signal of lesser power feeding the balanced optical splitter (241) that orients the split optical signals to the supply connectors of a consumer unit.

A fiber optic tray system includes a tray. The tray includes a tray body, the tray body extending along a longitudinal axis between a front and a rear and extending along a lateral axis between a first side and a second side. The tray further includes a plurality of alignment rails, each of the plurality of alignment rails protruding from the tray body along a transverse axis. The tray further includes a plurality of retainer features disposed at the rear of the tray body. The fiber optic tray system further includes a fiber optic module, the fiber optic module including an outer housing and at least one retainment feature. The at least one retainment feature is interfaced with at least one of the plurality of retainer features to retain the fiber optic module on the tray.

A cable spool module for a terminal module includes a skirt, a cable spool and a retention member. The cable spool may include a lower flange, an upper flange and a barrel disposed between the lower and upper flanges. The retention member may be configured to couple a terminal module to the cable spool. The skirt may be configured to be removed from the lower flange to permit access to the cable spool and the slack fiber optic cable wound on the cable spool.

An object to provide a submarine optical transmission apparatus capable of efficiently housing optical components and electric components. First component housing units can house either or both of an optical component and an electric component and are stacked in a Z-direction. A case can house the first component housing units and a longitudinal direction thereof is an X-direction. A heat dissipating member is disposed in the case and conducts heat generated in the first component housing units to the case.
