SYSTEM FOR CABLE STORAGE AND DEVICE MOUNTING PARTS
A system for routing at least two cables with fiber connectors without bending the at least two cables 90°. The system includes a base that has a plurality of female connectors. The system also has a module that includes a plurality of male connectors for releasably connecting to the base female connectors. The module includes a connector surface that supports at least one cable adapter for connecting the at least two fiber connectors. The connector surface is oriented at a non-orthogonal angle with respect to the base. The module includes a passageway that at least one of the at least two cables extends therethrough without bending 90°.
Aspects and techniques of the present disclosure relate to an enclosure (20) that can include first and second housing pieces (22, 24) that cooperate to define an enclosed interior (26) of the enclosure (20). The first and second housing pieces (22, 24) mate at an interface (28) that extends about a continuous sealing loop (30). The enclosure (20) may include a seal (44) that extends about the continuous sealing loop (30) of the enclosure (20) at the interface (28) between the first and second housing pieces (22, 24). The seal (44) can include a retention portion (46) positioned within a channel (36) of the first housing piece (22) and a sealing flap (48) connected to the retention portion (46). The second housing piece (24) may include an outer flange (50) that extends about the continuous sealing loop (30) of the enclosure (20). The sealing flap (48) of the seal (44) can be compressed between the outer flange (50) and a rim element (32) of the enclosure (20).
Latching system that latches an enclosure having a compressible sealant about its perimeter, the latching system providing for an open configuration, a staged configuration, and a mated configuration, the compressible sealant engaging a pair of projections having a channel therebetween to form a seal having an air gap above the sealant.
Aspects of the present disclosure relate to a modular fiber optic distribution system for enhancing installation flexibility and for facilitating adding components to a terminal housing over time so as to delay cost. The system is configured to allow components (e.g., inserts, add-on modules, etc.) to be readily added to the terminal housing over time to expand capacity, provide upgrades and to provide forward and backward compatibility.
An enclosure (10) includes a base (38) defining a splice region (148) and a cover (40) coupled to the base (38) to move between a closed position and an open position. A plurality of ruggedized adapters (26) are on the cover (40), each adapter having an inner port (64) and an outer port (66). A removable module (32) is disposed on the cover (40), at least one input fiber (12) being routed from the splice region (148) of the base (38) to the removable module (32), wherein the at least one input fiber (12) is output from the module as a pigtail (28) having a connectorized end that is connected to an inner port (64) of a ruggedized adapter (26). A cable input location (16) receives an input cable (14/20) including at least one tube (138) surrounding at least one fiber (12) that carries the same signal as the at least one input fiber (12) being routed from the splice region (148) to the removable module (32). The input cable (14/20) is anchored to the base (38) at the cable input location (16). A tube holder (150) is slidably mounted to the base (38) past the cable input location (16), wherein the tube holder (150) keeps separate an unused fiber-carrying tube (138) that is stored within the base (38) in a loop (122) from a fiber- carrying tube (138) whose fiber (12) leads toward the splice region (148) of the base (38) for further routing toward the removable module (32).
Aspects and techniques of the present disclosure relate to a fiber optic connector including a connector body defining a central longitudinal axis that extends in a front-to-rear orientation. The connector body can include a front connector housing piece and a rear connector housing piece that may be aligned along the central longitudinal axis. A front end of the rear connector housing piece can be adapted to connect with a rear plug end of the front connector housing piece. The rear end of the rear connector housing piece can include a unitary fiber bend radius limiting structure. The unitary fiber bend radius limiting structure can be generally funnel-shaped. A ferrule assembly can be captured between the front and rear connector housing pieces with the rear connector housing piece functioning as a rear spring stop.
