A method may include aligning a portion of each of a plurality of optical ribbons in a particular orientation or sequence using a set of alignment apparatus. The method may include stripping the portion of each of the plurality of optical ribbons to expose a cladding of each fiber of the plurality of optical ribbons using a set of stripping apparatus. The method may include hermetically sealing a tube around the portion of each of the plurality of optical ribbons using a set of sealing apparatus. The method may produce a hermetic optical fiber feedthrough.

An optical connection structure including N first inner housings, a first outer housing, N second inner housings, and a second outer housing. The respective first inner housings hold M first ferrules. The first outer housing holds the first inner housings in an arranged state. The respective second inner housings hold M second ferrules. The second outer housing holds the second inner housings in an arranged state. The optical connection structure includes a first latch mechanism that restrict a movement of the first inner housing relative to the first outer housing in a pullout direction, a second latch mechanism that couples the first inner housing and the second inner housing to each other, and a latch releasing mechanism that releases the first latch mechanism in a state where the first inner housing and the second inner housing are coupled to each other by the second latch mechanism.

An expanded beam connector for use with a fibre optic fibre is described, the expanded beam connector comprising; a body and at least one bore located within said body for accepting a fibre optic ferrule, wherein the perimeter of said bore comprises at least one channel extending from an open end of said bore. Methods of manufacturing an expanded beam connector are also described.

A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.

A fiber optic alignment device includes a first and a second alignment block and a first and a second gel block. A fiber passage extends from a first end to a second end of the fiber optic alignment device. The fiber passage is adapted to receive a first optical fiber through the first end and a second optical fiber through the second end. An intermediate portion of the fiber passage is positioned between the first and the second ends. The intermediate portion is adapted to align the first and the second optical fibers between the first and the second alignment blocks. A first portion of the fiber passage is positioned between the first end and the intermediate portion of the fiber passage. The first portion extends between the first alignment block and the first gel block. A second portion of the fiber passage is positioned between the second end and the intermediate portion of the fiber passage. The second portion extends between the second alignment block and the second gel block. End portions of the first and the second optical fibers may be cleaned when slid between the alignment blocks and the gel blocks. The fiber passage may include an undulating portion.

An adapter with novel alignment features engages alignment features on a plug, providing general alignment of the ferrule holders and ferrules in the plug. After the plug engages the adapter, the ferrule holders engage a second set of alignment features in the adapter to provide fine alignment for the ferrules.

A factory processed and assembled optical fiber arrangement is configured to pass through tight, tortuous spaces when routed to a demarcation point. A connector housing attaches to the optical fiber arrangement at the demarcation point (or after leaving the tight, tortuous spaces) to form a connectorized end of the optical fiber. A fiber tip is protected before leaving the factory until connection is desired.

A fiber optic connector with a pair resilient actuators positioned on an outer portion of an upper body portion of a cable boot assembly, when depressed allow a user to remove the cable boot assembly from a housing, rotate, and change polarity of the ferrules located within a front body secured to the cable boot assembly.

A terminus for a fiber optic cable has a ferrule with a fiber stub secured in a channel of the ferrule. The fiber stub has a polished forward end face. The fiber stub extends from a rearward end of the ferrule so that a rearward end face of the fiber stub is rearwardly spaced from the ferrule. An alignment member is axially aligned with the ferrule and has a channel extending between forward and rearward ends of the alignment member. The channel includes a fiber alignment portion in which the rearward end face of the fiber stub is received. The fiber alignment portion is statically configured to receive a forward end face of the filament of the fiber optic cable in opposed relationship to the rearward end face of the fiber stub and axially align the faces to each other.

An optic fiber adaptor includes two flexible engaging members and two positioning walls cooperating with one another to define an insertion slot. Each engaging member has a first inclined surface and a second inclined surface disposed behind the first inclined surface. A distance between the first inclined surfaces of the engaging members decreases rearwardly so as to facilitate pushing of a casing body of a ferrule assembly into the insertion slot. A distance between the second inclined surfaces of the engaging members decreases forwardly so as to facilitate pulling of the casing body out of the insertion slot. An optic fiber connecting device having the optic fiber adaptor is also disclosed.
