An optical connector mechanism includes an abutting portion that applies a pressing force so as to cause an end surface of a first optical transmission and reception path and an end surface of a second optical transmission and reception path to abut against each other, a first case that houses the first optical transmission and reception path, a second case that houses the second optical transmission and reception path, a sleeve case slidably attached to the first case, an elastic bar member including one end portion fixed to the first case and another end portion to be inserted into the second case, an engagement portion that engages the other end portion of the elastic bar member with the second case, and an engagement releasing portion that presses the elastic bar member so as to release the engagement performed by the engagement portion when the sleeve case slides.

A ferrule includes a ferrule body having a first opening formed in a side face thereof, and having a second opening formed in a top face thereof, wherein the first opening is configured to receive an optical waveguide inserted into the ferrule body at the side face, and wherein the second opening is formed over and in communication with the first opening, such that the second opening connects an inner space of the first opening to an outside of the ferrule body.

A ferrule pin clamp used for a ferrule into which a guide pin is inserted includes: a main body including a pin holder that holds a groove portion of the guide pin. The pin holder includes a pair of arcs. A diameter of the pair of arcs: is smaller than a maximum shaft diameter of the guide pin, and is larger than a shaft diameter of the groove portion of the guide pin.

A connector member fixes an optical fiber. The connector member includes an optical fiber; a clamping member that clamps the optical fiber; and a friction imparting member that is interposed between the optical fiber and the clamping member.

An optical fiber connection system includes a first and a second optical fiber, each with end portions that are terminated by a first and a second fiber optic connector, respectively. A fiber optic adapter connects the first and the second fiber optic connectors. A fiber alignment apparatus includes V-blocks and gel blocks. Each of the fiber optic connectors includes a connector housing and a sheath. The end portions of the optical fibers are positioned beyond distal ends of the respective connector housings. The sheath is slidably connected to the connector housing and slides between an extended configuration and a retracted configuration. The sheath covers the end portion of the respective optical fiber when the sheath is at the extended configuration and exposes the end portion when at the retracted configuration. The end portions of the optical fibers are cleaned when slid between the V-blocks and the gel blocks.

A field installable fiber optic connector for use with polymer optical fibers includes a housing that releasably connects to another optical device. A mechanical termination assembly is located in the housing to mechanically terminate a plurality of individual fibers of the polymer optical fibers. Ferrules are supported by the housing. Each ferrule is positioned to receive one of the individual fibers from the mechanical termination assembly.

An optical fiber alignment assembly may comprise an alignment fixture including a groove configured to engage first and second optical fiber ferrules, a first clamping mechanism configured to selectively apply a force on the first optical fiber ferrule to constrain motion of the first optical fiber ferrule within the groove, and a second clamping mechanism configured to selectively apply a force on the second optical fiber ferrule to constrain motion of the second optical fiber ferrule within the groove.

An optical module unlocking apparatus includes a housing, including a base and a mounting portion connected to one end of the base. The base has an accommodation area for installing a circuit board and an electrical component. The apparatus also includes an unlocking component, including an unlocking arm movably connected to the housing. The unlocking arm has an abutment portion for abutting against an elastomer of a cage, and the unlocking component is configured to push the unlocking arm outward relative to the housing in an insertion direction under an action of external force to separate the abutment portion from the elastomer. The apparatus further includes an elastic component on an outer side surface of the mounting portion and outside the accommodation area. A first end of the elastic component is connected to the mounting portion and a second end of the elastic component is connected to the mounting portion.

A connector for connection to a mating connector includes a connector housing having a contact chamber configured to accommodate a contact assembly extending from a contact side toward a mating side, and a secondary retention means having two mounting arms and a securing element disposed therebetween. The connector housing has an access opening. The secondary retention means is movable between a pre-latched and a final latched position. One of the mounting arms has a first latching unit which, in the final latched position, is connected to a first mating latching unit disposed on the connector housing. One of the mounting arms has a locking element extending away parallel to a mating axis, which in the pre-latched position, blocks connection to the mating connector. In the final latched position, the securing element extends through the access opening into the contact chamber and locks the contact assembly in place.
