It is an object of the present invention to accurately maintain a positional relationship between a lens held in a holding member and an optical fiber without requiring any complicated operation. The invention includes a holder (11), at one end of which a housing section (11c) that houses a ball lens (12) is formed and at the other end of which an insertion hole (11a) for inserting an optical fiber (13) is formed, and a magnet (14) provided outside in a direction crossing a housing direction of the ball lens at the one end of the holder, in which the magnet generates an attracting force for aligning a center of the ball lens with a center of an optical element provided in a coupling target.

A fiber optic ferrule coupling system including a ferrule interface plate having a ferrule port extending therethrough and a pocket in a side of the ferrule interface plate adjacent to the ferrule port, wherein a spring element disposed in the pocket partially protrudes into the port and applies an adjustable spring force to a ferrule connector inserted in the ferrule port via a spring cover fittable within the pocket.

A fiber enclosure with an integrated enclosure mounting system includes a base, a cover, and a clamp for securing the cover to the base. The base has an end wall with through openings extending therethrough and has a fiber management mounting frame provided on an inner side of the end wall. The mounting frame is configured to receive fiber management trays and the cover is engageable over the mounting frame and into abutment with the base and is securable to the base by the clamp to fully enclose the mounting frame and fiber management trays within a cavity formed between the cover and the base. The base also includes enclosure mounting sockets formed on an outer side surface thereof. The enclosure mounting sockets are releasably engageable with complementary shaped mounting post provided on a mounting arm to releasably secure the base to the mounting arm.

A composite structure includes a base and an auxiliary portion of dissimilar materials. The auxiliary portion is shaped by stamping. As the auxiliary portion is stamped, it interlocks with the base, and at the same time forming a desired structured feature on the auxiliary portion, such as a structured reflective surface, an alignment feature, etc. With this approach, relatively less critical structured features can be shaped on the bulk of the base with less effort to maintain a relatively larger tolerance, while the relatively more critical structured features on the auxiliary portion are more precisely shaped with further considerations to define dimensions, geometries and/or finishes at relatively smaller tolerances. The auxiliary portion may include a composite structure of two dissimilar materials associated with different properties for stamping different structured features.

One example includes an optical interconnect device. The optical interconnect device includes a plurality of optical fiber ports coupled to a body portion. The optical interconnect device also includes a plurality of optical fibers that are secured within the body portion. A first portion of the plurality of optical fibers can extend from a first of the plurality of optical fiber ports to a second of the plurality of optical fiber ports, and a second portion of the plurality of optical fibers can extend from the first of the plurality of optical fiber ports to a third of the plurality of optical fiber ports.

An optical fiber includes: a core; and a clad which is formed so as to surround an outer circumference of the core concentrically with the core, the clad having at least an inner cladding layer adjacent to the outer circumference of the core and an outer cladding layer formed on an outer circumference of the inner cladding layer, wherein a refractive index of the outer cladding layer is Δ3, and an outer circumference radius of the outer cladding layer is r3, a relationship of Δ1max>Δ3>Δ2min is satisfied, a relationship of Δ3−Δ2min≦0.08% is satisfied, a relationship of r1<r2<r3 is satisfied, a relationship of 0.35≦r1/r2≦0.55 is satisfied, a cable cut-off wavelength is less than or equal to 1260 nm, and an MFD at a wavelength of 1310 nm is 8.6 μm to 9.2 μm.

A fixture includes a base portion and a pair of holding portions on the base portion. Each holding portion include a clamping portion for clamping an object, and a head portion on the clamping portion side opposite to the base portion side. Each head portion includes a through-hole for a fastening member for adjusting a gap between the holding portions. The rigidity of the clamping portions is smaller than the rigidity of the head portions, with respect to deformation caused by the fastening member. The distance from the base portion to end portions of the holding portions in a plane orthogonal to the axial direction of the object is determined according to the tolerance prescribed for the object. The gap when external force is not being applied by the fastening member is determined according to an allowable amount of stress to be applied to the object.

An optical connector for an endoscope has a first holding member which holds a first waveguide therein, a second holding member which holds a second waveguide therein and replaceable replacement members which intervenes between the first holding member and the second holding member so that replacement waveguides intervenes between the waveguides and is optically coupled to the waveguides. The optical connector has attachment members and a positioning mechanism which positions the holding members and the replacement members relative to one another.

A messenger wire hanger includes a body having integral first, middle, and hook portions. The hook portion is in the shape of a hook adapted to hook over a messenger wire. The body defines a first opening between the first portion and the middle portion and a second opening between the middle portion and the hook portion. A lashing strap has a first portion and a second portion with the first portion of the lashing strap being disposed in the first opening of the body and the second portion of the lashing strap being disposed in the second opening of the body. Another configuration uses three openings with a second pawl extending between the second and third openings to define a tortuous path for the lashing strap.

A fiber optic cable clamp has two identical halves that snap together forming the clamp. The clamp can be made of thermoplastic materials and designed to permit stacking of multiple clamps without damaging the cables.
