Pushable Multi-Fiber Connector
Multi-fiber, fiber optic cable assemblies may be configured so that the terminal ends of the cables have pre-assembled back-post assemblies that include pre-assembled ferrules, such as MPO ferrules that meet the requisite tolerances needed for fiber optic transmissions. To protect the pre-assembled components from damage prior to and during installation, pre-assembled components may be enclosed within a protective housing. The housing with pre-assembled components may be of a size smaller than fully assembled connectors so as to be sized to fit through a conduit. The remaining connector housing components for the multi-fiber connectors may be provided separately and may be configured to be attached to the back-post assembly after installation of the cable.
Fiber optic cable with flexible conduit
The present disclosure relates to a fiber optic cable that includes a plurality of internal optical fibers and a fiber optic cable portion. The fiber optic cable portion includes an outer jacket and an inner conduit, the inner conduit containing the plurality of optical fibers disposed therein. The fiber optic cable further includes a flexible conduit portion, wherein the flexible conduit portion has a proximal end and a distal end. The proximal end is secured to the fiber optic cable portion and the distal end has a terminating device. The terminating device at least partially encases the flexible conduit portion, and the plurality of optical fibers passes through the flexible conduit portion and the terminating device.
FIBER OPTIC CABLE ASSEMBLIES HAVING EXPOSABLE CABLE LEGS FOR SUPPORTING MULTIPLE DEPLOYMENT SCENARIOS
Fiber optic cable assemblies having a construction suitable for a first deployment scenario where the optical connection is made to the device externally that may be transformed for a second deployment scenario where the optical connection is disposed within an internal cavity of the device are disclosed. The cable assembly has one or more cable legs disposed within a profile support element and are disposed under the heat shrink. The fiber optic connectors are exposed and suitable for optical connection with the heat shrink intact on the cable assembly and the profile support element further provides further flexibility using different outer housings with the cable assembly when making external optical connections to the device Thus, the concepts disclosed advantageously allow a single cable assembly to support multiple deployment scenarios in the field, thereby reducing complexity.
Pass-through assembly having an anchor member and a cover
Anchoring an input cable (190) at an input port (123, 223) of an enclosure (110) includes inserting the input cable (190) through an anchor member (151, 251) so that a cable jacket (191) terminates within the anchor member (151, 251) and at least one optical fiber (195) extends outwardly from the anchor member (151, 251). The anchor member (151, 251) is secured to the cable jacket (191) using the sheath (175). A cover (162, 260) is mounted to the anchor member (151, 251) to form a pass-through assembly (150, 250) defining an enclosed region. Material is injected into the enclosed region to fix strength members (197) and/or optical fibers (195) of the input cable (190) to the pass-through assembly (150, 250). The ruggedized pass-through assembly (150, 250) is disposed at a base (120, 220) of the enclosure (110).
Indexing architecture including a fan-out arrangement
The present disclosure relates to fiber optic components and structures for use in building fiber optic networks using an indexing architecture. In certain examples, fan-out structures are used.
Pass-through assembly having an anchor member and a cover

Fiber optic connectors and sub-assemblies with strength member retention
The disclosure relates to a fiber optic connectors and sub-assemblies having a retention body for connectorizing a fiber optic cable along with fiber optic connectors and methods therefor. In one embodiment, the sub-assembly comprises a cable lock comprises a cable channel for receiving a fiber optic cable therethrough, and at least one strength member engagement surface. The retention body comprises an optical fiber channel for receiving an end portion of at least one optical fiber of the fiber optic cable therethrough, and at least one strength member engagement surface. The strength member engagement surfaces of the cable lock and the retention body are configured to cooperate with each other to receive and retain at least one strength member of the fiber optic cable. Other fiber optic connector sub-assemblies are also disclosed.
Universal optical fiber connector
The present invention relates to a universal optical fiber connector including a hot-melt end connector assembly, a heat-shrinkable sleeve and a protective shell for the heat-shrinkable sleeve. The assembly further comprises the main body of the hot-melt end, and a ceramic ferrule, a wedge for the ceramic ferrule and a pre-embedded optical fiber passing through the main body. The tail end of the protective shell for the heat-shrinkable sleeve is connected with an optical fiber locking device for the locking of the optical fiber; the locking device and the protective shell for the heat-shrinkable sleeve are separately configured. The present invention is applicable to optical fibers of different sizes and can improve the tensile properties of the optical fiber connector, and the protective shell for the heat-shrinkable sleeve can be volume-produced with the same mould instead of being produced independently for each type, so as to improve the production efficiency.
