Connector assemblies for insertion into a port structure of a telecommunication enclosure to provide an environmentally sealed connection are disclosed herein. An exemplary connector assembly includes a forward connector housing, an intermediate body positioned over a portion of the forward connector housing, an optical connection portion coupled to the forward connector housing, and an adapter, positionable over the intermediate body. The intermediate body comprises a forward portion and a rearward portion, with the forward portion including an external key and a plurality of trigger elements. Each trigger element has a foot portion and a locking portion, and the rearward portion includes an orientation key in substantial alignment with the external key.

The present invention discloses a type of optical fibre connector, comprising: an external shell; an internal shell, installed within said external shell; an inserted core component, contained within said internal shell and comprising an inserted core and a length of optical fibre pre-installed within said inserted core; and a spring, contained within said internal shell and located behind said inserted core, and being for exerting a pre-set axial force on said inserted core. Said internal shell includes a front part and a rear part; said rear part is assembled on said front part. Additionally, said spring is compressed between said rear part and said inserted core. In the present invention, the rear part can act as a retainer for the compressed spring and can also be for securing the Kevlar fibre extension tube of the optical cable. As a result, in comparison to the prior art, the present invention reduces the number of components of the optical fibre connector and simplifies the structure of the optical fibre connector, thus facilitating rapid on-site assembly of the optical fibre connector.

A fiber optic connector (20) including a ferrule (42) having a front end (48) and a rear end (50). The ferrule (42) defines an axial bore (46) that extends through the ferrule (42) between the front end (48) and the rear end (50). The ferrule (42) includes a ferrule axis (64) that extends along the axial bore (46). The fiber optic connector (20) includes an optical fiber (62) positioned within the axial bore (46) that is movable relative to the ferrule (42) within the axial bore (46) along the ferrule axis (64). The optical fiber (62) has fiber end face (63) that has been energy treated to round the fiber end face (63). A fiber alignment structure (66) can be attached at a front ferrule end face (54) of the ferrule (42). A camera can be used to position a fiber end face (63) of the optical fiber (62) relative to the front ferrule end face (54) of the ferrule (42).

A fiber optic cable and connector assembly is disclosed. In one aspect, the assembly includes a cable optical fiber, an optical fiber stub and a beam expanding fiber segment optically coupled between the cable optical fiber and the optical fiber stub. The optical fiber stub has a constant mode field diameter along its length and has a larger mode field diameter than the cable optical fiber. In another aspect, a fiber optic cable and connector assembly includes a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including an expanded beam fiber segment supported within the ferrule. The expanded beam fiber segment can be constructed such that the expanded beam fiber segment is polished first and then cleaved to an exact pitch length. The expanded beam fiber segment can be fusion spliced to a single mode optical fiber at a splice location behind the ferrule.

The present disclosure relates to an optical splice package for splicing together first and second optical fibers or first and second sets of optical fibers. The optical fibers have elastic bending characteristics. The splice package includes a splice housing including a mechanical alignment feature for co-axially aligning ends of the first and second optical fibers or sets of optical fibers within the splice housing. The splice housing contains adhesive for securing the ends of the first and second optical fibers or sets of optical fibers within the splice housing. The optical package has a weight less than a spring force corresponding to the elastic bending characteristics of the first and second optical fibers or sets of optical fibers.

A connector assembly for a fiber optic cable comprises a multi-part inner housing adapted to support an optical fiber splice connection structure. A cable clamp is located at a proximal end of the inner housing and is adapted to engage an outer sheath of a fiber optic cable. Preferably, the cable clamp is rotatable with respect to the inner housing.

Methods for cleaving an optical fiber that extends from a ferrule are provided herein. The ferrule can be aligned on a first side of a scribe wire and an unconstrained end of the optical fiber on a second side of the scribe wire. Tension can be applied to the scribe wire with the optical fiber. Relative motion between the scribe wire and the optical fiber can be caused, while the tension is applied with the optical fiber. The scribe wire and the optical fiber can be separated. A fiber optic shard can be cleaved from the optical fiber. The fiber optic shard may include the unconstrained end of the optical fiber.

An optical fiber connector includes a housing configured to mate with a receptacle, a collar body that includes a fiber stub and a mechanical splice device, a backbone to retain the collar body within the housing, and a boot. The backbone includes at least one guide channel to facilitate wrapping strength members of an optical fiber cable around the backbone and a cable jacket clamping portion to clamp the cable jacket of the cable. The boot actuates the cable jacket clamping portion of the backbone upon attachment to the backbone.

The present disclosure relates to an optical fiber alignment device that has an alignment housing that includes first and second ends. The alignment housing defines a fiber insertion axis that extends through the alignment housing between the first and second ends. The alignment housing includes a fiber alignment region at an intermediate location between the first and second ends. First and second fiber alignment rods are positioned within the alignment housing. The first and second fiber alignment rods cooperate to define a fiber alignment groove that extends along the fiber insertion axis. The first and second fiber alignment rods each having rounded ends positioned at the first and second ends of the alignment housing.

An optical receptacle includes an optical component assembly, a tubular sleeve, and a tubular shell. The optical component assembly includes a light guide member, a tubular member, which retains the light guide member in the through hole, and projections, which extends outward of an outer peripheral surface of the tubular member at one end. The sleeve is fitted to the outer periphery of the light guide member at a rear end portion. The inside diameter of a front portion of the sleeve differs from that of the rear end portion. The shell covers the outer peripheral surface of the sleeve and includes a groove in a rear end portion. The groove extends in an axial direction and turns and extends in a circumferential direction. The groove is engaged with the projections of the tubular member to secure the shell. The shell and the sleeve are attachable and detachable.
