A fiber optical connector includes a connector housing and an optical-fiber component. The connector housing comprises a receiving space. One end of the connector housing forms a connector opening communicating with the receiving space. Two side walls of the connector housing comprise a plurality of buckling portions adjacent to the connector opening. The optical-fiber component is positioned in the receiving space. The optical-fiber component comprises a sleeve piece. The sleeve piece comprises a block member and a threaded portion. The block member is assembled in the connector opening and the block member fully received inside the receiving space. Two sides of the block member respectively form an engaging portion. Each of the engaging portions is engaged with the corresponding buckling portion, and the threaded portion is exposed on the peripheral surface of a tail portion of the sleeve piece and out of the connector opening.

A fiber optic ferrule sub-assembly for insertion into an outer housing of a fiber optic connector includes a ferrule assembly having a ferrule that forms an optical communication connection with another fiber optic device. A back housing includes a back post to be attached to a fiber optic cable. A spring is operatively disposed between the ferrule assembly and the back housing. A linkage connects the ferrule assembly to the back housing such that the spring is compressed and biases the ferrule away from the back housing prior to insertion of the fiber optic ferrule sub-assembly into the outer housing.

The present disclosure relates to a ferrule boot for mounting in a multi-fiber ferrule. The ferrule boot may include a body member that has a distal end and a proximal end. The body member may define a plurality of openings that extend lengthwise therethrough with each opening being configured for receiving a respective one of a plurality of optical fibers.

A connectorized fiber optic cabling assembly includes a loose tube fiber optic cable and a connector assembly. The cable has a termination end and includes an optical fiber bundle including a plurality of optical fibers, at least one strength member, and a jacket surrounding the optical fiber bundle and the strength member. The connector assembly includes a rigid portion and defines a fiber passage. The connector assembly is mounted on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the fiber passage. The plurality of optical fibers undergo a transition from a ribbonized configuration to a loose, non-ribbonized configuration in the rigid portion of the connector assembly.

Embodiments of the disclosure relate to an optical fiber cable having at least one optical fiber, a cable jacket and a foam layer. The cable jacket includes an inner surface and an outer surface in which the outer surface is an outermost surface of the optical fiber cable. The inner surface is disposed around the at least one optical fiber. The foam layer is disposed between the at least one optical fiber and the cable jacket. The foam layer is made of an extruded product of at least one thermoplastic elastomer (TPE), a chemical foaming agent, and a crosslinking agent. The foam layer has a closed-cell morphology having pores with an average effective circle diameter of less than 100 μm. Further, the foam layer has a compression modulus of less than 1 MPa when measured at 50% strain.

A fiber optic connector has a plug region at a first axial end and an anchor region at a second axial end. The anchor region includes first interlock members which protrude outwardly from a support portion. A crimp sleeve can be disposed over the anchor region of the plug connector so that a surrounding portion (e.g., a jacket and/or strength members) of the cable extends between the crimp sleeve and the first interlock members. When the plug connector is assembled, second interlock members can be formed in the crimp sleeve to extend radially into gaps between the first interlock members to enhance retention of the surrounding portion of the cable therebetween.

Fiber optic connectors having improved cable termination for attaching the strength members of a fiber optic cable to a crimp body along with cable assemblies and methods of making the same are disclosed. The fiber optic connectors and cable assemblies provide a robust cable termination so that the fiber optic jacket of the fiber optic cable is inhibited from slipping relative to the fiber optic connector when tensile force are applied to the terminated cable. The fiber optic connector allows a mechanical attachment of the strength members of the cable to a crimp body having first and second shells with respective through windows at a rear portion. One or more strength members of the cable are routed from an interior passage of the crimp body through the respective through windows so that the strength members may be secured between an outer barrel of the crimp body and a crimp band for transferring tensile forces to the strength members, rather than the cable jacket.

An optical fiber connector can terminate a plurality of optical fiber cables, each with a jacket encasing at least one optical fiber and a strength element. A connector housing has a back post. The optical fibers of the plurality of optical fiber cables extend into the connector housing through the back post. A single crimp ring crimps the strength members of the plurality of optical fiber cables onto the back post. In a method of terminating a plurality of optical fiber cables, the cables are inserted through a single crimp ring, optical fibers of each of the cables are terminated in a multifiber ferrule, the cables are loaded into a back body of a connector housing, and strength members of the cables are crimped onto a back post using a single crimp ring.

A fiber optic connector includes a housing and push-pull boot with a latch body disposed between a front extension of the push-pull boot and a top side of the housing. The latch body has an anti-buckle feature, which may be a projection. The anti-buckle feature movable between a relaxed position and a stressed position, wherein the anti-buckle feature is in contact with the housing in the stressed position to prevent the latch body from buckling.

An optical fiber feed-through connector for optically coupling an end portion of an optical fiber cable with a non-feed-through optical fiber connector includes a feed-through duct engaging portion having a body member and a compression fitting portion configured to radially compress a portion of the body member around the free end portion of the duct and a feed-through housing portion configured to be operatively coupled to the feed-through duct engaging portion so as to allow the end portion of the optical fiber cable to be slidingly fed through the feed-through housing portion. The feed-through engaging portion is configured to permit the end portion of the optical fiber cable to be slidingly fed through both the duct and the feed-through duct engaging portion, and the feed-through duct engaging portion and the feed-through housing portion are configured to permit the optical fiber cable to be pushed or pulled through the duct and the feed-through housing portion after the feed-through duct engaging portion is operatively coupled to the feed-through housing portion.
