A pluggable free-space photoelectric hybrid connector including a female connector and a male connector is provided. The female connector includes a first insulating substrate, metal elastic clips, a first circuit board, and a first optical communication module. An insertion cavity is formed at the front end of the first insulating substrate, and a first fiber mounting hole and first electrode mounting holes are formed at the rear end thereof. The metal elastic clips are mounted in the first electrode mounting holes respectively, where contact portions of at least one set of metal elastic clips are exposed from the top of the insertion cavity, and contact portions of at least another set of metal elastic clips are exposed from the bottom of the insertion cavity. The first circuit board is mounted at the rear end of the first insulating substrate and is electrically connected to the metal elastic clips.

A multi-fiber ferrule has lenses that have different prescriptions to disperse the light emitted from the multi-fiber ferrule. Alternatively, the lens for each individual optical fiber can be moved relative to the optical fiber or the optical fiber opening in the multi-fiber ferrule to cause the laser beam exiting the multi-fiber ferrule to be redirected into a structure that absorbs or blocks the laser.

A new boot for a fiber optic connector has a ribbed back portion, a center portion, and a forward extending portion that can be used to insert and remove the fiber optic connector to receptacle. The ribbed back portion has grasping elements and is connected to the center portion. The center portion is removably connected to a crimp body that is in turn connected to the connector housing. The front extension is connected to the fiber optic connector and also provides a keying feature depending on the side of the fiber optic connector on which it is installed.

A cable sealing device including an attaching part securable to the cable; a fixation part adapted to be mountable on the attaching part; and a sealing part. The attaching part includes outer locking faces. The fixation part has inner abutment faces adapted to co-operate with the outer locking faces to axially and rotationally lock the fixation part relative to the attaching part. The sealing part includes an inner seal and an outer seal. The sealing part also includes a second securing arrangement that is configured to engage a first securing arrangement of the fixation part to axially and rotationally lock the sealing part to the fixation part.

Male plug fiber optic connectors having configured for mating with a dissimilar connector are disclosed along with cable assemblies using the same. The fiber optic connector comprises a ferrule, a connector housing, and a nose-piece having a pocket disposed at a front portion. The pocket of the nose-piece is configured for allowing optical mating with a dissimilar connector. In one embodiment, the pocket on the nosepiece of the connector is disposed on a forward portion of the nosepiece. The fiber optic connectors disclosed advantageously allow for optical mating with dissimilar optical connectors with a quick and easy assembly for rugged applications or other optical communication networks.

The present disclosure discloses an optical element for measuring a change in strain. The optical element has ends and first and second portions for guiding light which extend between the ends of the optical element and are mechanically coupled to each other at at least one position. Each of the first and second portions for guiding light comprise at least one Bragg grating. The optical element is arranged such that, when an axial or uniaxial strain is equally applied to the first and second portions for guiding light at the ends of the optical element, an optical response from the at least one Bragg grating of the first portion for guiding light differs from an optical response form the at least one Bragg grating of the second portion for guiding light.

A method for manufacturing an intermittently coupled-type optical fiber ribbon includes arranging a plurality of optical fibers in parallel in a direction orthogonal to a longitudinal direction of the plurality of optical fibers, coating all of the plurality of optical fibers with a coupling resin, intermittently inserting a cleaving blade into the coupling resin between some adjacent optical fibers of the plurality of optical fibers to form slits. An outer diameter of each of the optical fibers is 220 μm or less. A distance between the optical fibers into which the cleaving blade is inserted among the adjacent optical fibers is 10 μm or more and 100 μm or less.

An anti-theft merchandise hook that includes a top wire connected to a housing at a first end of the top wire, and to a mounting portion, used to mount the anti-theft merchandise hook to a stationary surface, at a second end of the top wire opposite the first end. A bottom wire is attached to the mounting portion and extends from the mounting portion towards the housing. The bottom wire is configured to hold retail merchandise. A hanger is at least partially disposed within the housing. The hanger is configured to move between a closed position in which the hanger abuts the bottom wire, and an open position in which the hanger is spaced some distance from the bottom wire. A motor is configured to move the hanger between the closed position and the open position.

An apparatus includes a body with an opening through the body, the opening corresponding to dimensions of a cable to be connected to a circuit board and a flat surface to abut the circuit board. The apparatus further includes one or more attachment mechanisms to attach the body to the circuit board.
