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.

A fiber optic adapter includes a first side wall (110), a second side wall (112) opposite the first side wall, a top wall (114), and a bottom wall (116) opposite the top wall. A cavity (10) is defined by the top wall, the bottom wall, the first side wall, and the second side wall, and an optical fiber alignment device (20) is situated in the cavity. The top wall (114) has an opening (117) therein, and a cover (118) is configured to selectively close the opening.

A fiber array unit (FAU) includes a substrate, a plurality of optical fibers, and a lid. The substrate includes: an optical window extending through a layer of non-transparent material, a plurality of grooves, and an alignment protrusion configured to mate with an alignment receiver. The plurality of optical fibers are disposed in the plurality of grooves. The alignment protrusion is configured to align the plurality of optical fibers with an external device when mated with the alignment receiver. The plurality of optical fibers is disposed between the lid and the substrate.

The present invention relates to an optical connection device for optically connecting a first connector (42) of a first optical fiber device (44) with a second connector (46) of a second optical fiber device (48) along an optical axis, which comprises a plug part (40) having an elongated shaft (58) having a longitudinal shaft axis (62) and a lumen (60) extending through the shaft (58) along the shaft axis (62) for receiving the first connector (42), the plug part (40) further having a cap (64) at a first end of the shaft (58) which has an insertion opening (66) for insertion of the first connector (42) into the lumen (60), the opening (66) being aligned and communicating with the lumen (60), the plug part (40) having an optical window (68) having a solid body element (69), wherein the plug part (40) is at least in part deformable; and a clamp part (18), wherein the plug part (40) is configured to be at least partially inserted into the clamp part (18), and the clamp part (18) is configured to, when the plug part (40) is at least partially inserted in the clamp part (18) and when the first connector (42) is inserted into the lumen (60) of the shaft (58) of the plug part (40), exert a force onto the plug part (40) which deforms the plug part (40) upon tightening the clamp part (18) so as to clamp and hold the first connector (42) in position and orientation with respect to the optical axis.

An optical fiber connector is provided. A receptacle has an angled interior surface that acts to guide an optical fiber into the correct position as a jack is inserted into the receptacle.

The present disclosure relates to fiber optic connection systems including fiber optic connector having retractable noses for protecting bare fiber ends of ferrule-less connectors. In certain examples, the retractable noses are used in combination with protective shutters. In other examples, the retractable noses can accommodate multiple optical fibers.

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.

An optical fiber connector includes an adaptor having an insertion hole and first and second plugs holding, respectively, first and second optical fibers. The adaptor has first and second attracting surfaces having, respectively, one and the other insertion ports of the insertion hole. The first plug has a first attracted surface that receives, from the first attracting surface, an attractive force generated by a magnetic force when the first optical fiber is inserted into the one insertion port. One of the first attracting surface and the first attracted surface is constituted by a permanent magnet, and the other one thereof is constituted by a magnetic body. In a connection state between the first and second optical fibers, at least the outer peripheral edge of the first attracted surface does not continuously contact the outer peripheral edge of the first attracting surface.

The present disclosure relates to a fiber optic adapter having a footprint/form factor compatible with an SC adapter mounting structure or an LC adapter mounting structure or both the SC and LC adapter mounting structures. The adapter body may include first and second co-axially aligned connector ports for respectively receiving first and second fiber optic connectors. The fiber optic adapter may also include a fiber alignment structure configured to accommodate at least 12 optical fibers (e.g., 12 non-ferrulized optical fibers) for each of the first and second connector ports. Another aspect of the present disclosure relates to a fiber optic adapter with linearly moveable, spring biased shutters. A further aspect of the present disclosure relates to a ferrule-less fiber optic connector that may include a telescopic shroud and a safety lock for locking the shroud in a fiber protecting position. A further aspect of the present disclosure relates to a ferrule-less fiber optic connector with a spring-biased fiber holder.
