A fiber optic ferrule with rear holes and a guide pin clamp allows for changing guide pins in the field. The guide pin clamp has a forward clamp portion to engage the rear face of the fiber optic ferrule, a rearward clamp portion configured to engage the biasing spring, and a guide pin retaining plate. The guide pin retaining plate is movable from a first position to a second position to allow for the removal or insertion of guide pins.

A method of securing an optical fiber to a ferrule includes disposing an adhesive composition in a fiber-receiving passage of the ferrule to form a ferrule adhesion system. The adhesive composition in the ferrule adhesion system comprises a polymeric material in a solid form. The method also involves assembling an optical connector with the ferrule adhesion system, heating the ferrule in the optical connector to melt the adhesive composition, and inserting the optical fiber into the fiber-receiving passage of the ferrule and into contact with the adhesive composition that has been melted. The adhesive composition bonds the optical fiber to an inner surface of the ferrule upon cooling and solidifying.

A connector plug arrangement (330, 600, 700) includes a connector body (334, 610, 720); and an indication component (335, 650, 750). The indication component (335, 650, 750) includes a first portion (337, 653, 751) that is disposed at a rear end of the connector body and a second portion (339, 654, 753) that extends outwardly from the first portion (337, 653, 751). The first portion (337, 653, 751) is configured to extend along a circumferential perimeter of the connector body (334, 610, 720). The second portion (339, 654, 753) is configured to extend along the longitudinal axis of the connector body (334, 610, 720).

A fiber optic adapter is disclosed. The fiber optic adapter includes a main body configured to receive a first fiber optic connector through a first end and a second fiber optic connector through a second end for mating with the first fiber optic connector. The adapter includes a ferrule alignment structure located within an axial cavity of the main body, the ferrule alignment structure including a sleeve mount and a ferrule sleeve, the sleeve mount including an axial bore and at least one latching hook extending from a center portion of the sleeve mount toward the first end of the main body and at least one latching hook extending from the center portion toward the second end of the main body, the latching hooks configured to flex for releasably latching the first and second fiber optic connectors to the fiber optic adapter. The sleeve mount and the main body of the fiber optic adapter are unitarily molded as a single piece and the ferrule sleeve is separately placed within the axial bore of the sleeve mount.

Device for the coaxial connection of fiber-optic cables, comprising a single-piece coupling housing (10) and a single-piece sleeve mount (20), the sleeve mount (20) being designed with at least one latching nose (21) and the coupling housing (10) being designed with at least one latching mount which complements the at least one latching nose (21), wherein the latching mount is designed with at least one latching hook (14) and at least one stop (15).

A method of securing an optical fiber to a ferrule includes: heating an adhesive composition that is disposed within the ferrule to melt the adhesive composition; inserting the optical fiber into a fiber-receiving passage defining an inner surface of the ferrule and into contact with the melted adhesive composition; and cooling the melted adhesive composition. The adhesive composition is a solid material disposed within the fiber-receiving passage of the ferrule and in contact with the inner surface of the ferrule prior to the heating step. Additionally, the adhesive composition comprises a partially cross-linked resin and a coupling agent that covalently bonds the partially cross-linked resin to respective inorganic surfaces of the optical fiber and the ferrule following the cooling step.

Various connector housings for securing an optical cable, as well as methods of use and manufacture thereof are disclosed. A single-piece unitary connector housing body may include a first opening formed in a first end of the housing body, a second opening formed in a second end of the housing body, a bore through the housing body extending from the first opening to the second opening, and a back post surrounding the second opening. The first opening may be configured to receive a terminating optical cable and the second opening may be configured to receive a fiber optic cable. The back post may extend from the second opening in a longitudinal direction and may include a plurality of protrusions thereon. A length of the back post may have a concave shape.

The cable termination may include a housing and a cable having at least one conductor disposed within the housing with an elastomeric body disposed in the housing and constrictively stretched over a portion of the cable. A retainer may be disposed around a portion of the cable for retaining the elastomeric body on the cable. The cable termination may also include an enclosure capable of changing volumetrically in response to fluctuating pressure disposed in the housing and around a portion of the cable.

(Problem) To provide an optical ferrule that can easily accommodate multicore optical fibers, without an accompanying increase in the number of components. (Resolution Means) The optical ferrule 1 includes a guide opening 14 formed by an upper wall 10, a bottom wall 11, and a pair of side walls 12 and 13; a guide part 15 that extends forward from the upper wall 10 and the guide opening 14; and an optical coupler 20 provided on the upper surface of the upper wall 10. The optical coupler 20 has a waveguide aligning part 21 that aligns and holds an optical waveguide 2, and a light direction converter 22 that changes the direction of light from the optical waveguide 2 and emits the light toward an opposing optical ferrule 1.

A plug part which has at least one plug part housing having at least one elongate plug region for establishing a plug connection with another plug part in a plug-in direction, wherein the plug region has at least one electrical and/or optical plug contact for establishing at least an electrical and/or optical connection with the other plug part, and at least one step is arranged between the plug region and the rest of the plug part housing, wherein the plug part housing is of integral design and the plug region has an outer contour, wherein the outer contour, apart from the ends thereof which are at the end faces as seen in the plug-in direction, is designed to be free of recesses over the entire longitudinal extent thereof in the plug-in direction, or, with at least one recess.
