A bend inducing fiber array unit is provided comprising first and second anti-recovery plates and a V-groove chip. Opposing lateral anti-recovery plates are arranged on opposite sides of the first and second anti-recovery plates. Lateral edges on a common side of the anti-recovery plates are secured to a common face of one of the opposing lateral anti-recovery plates to fix the first and second anti-recovery plates relative to each other. A guided portion of the array of optical fibers is positioned in the fiber accommodating grooves of the V-groove chip and the V-groove chip is secured to the second anti-recovery plate such that the fiber accommodating grooves and a fiber guiding face of the first anti-recovery plate are fixed at a relative angle θ approximating the bend in the array of optical fibers.

The present invention relates to an optical interconnection component enabling implementation of optical fiber connection with higher accuracy than by the conventional technologies. The optical interconnection component is configured to maintain arrangement of end faces of a plurality of rotationally-aligned MCFs, so as to reduce connection loss to another component. Since arrangement of the MCFs can be confirmed by markers provided on a holding portion holding the plurality of MCFs inside, it becomes feasible to achieve the optical connection with higher accuracy.

A light coupling unit for use in an optical connector includes a waveguide alignment member that receives and aligns at least one optical waveguide. The light coupling unit includes a light redirecting member that has an input surface configured to receive input light from the end face of the optical wave guide. A curved reflective surface of the light redirecting member receives light from the input surface propagating along an input axis and redirects the light such that the redirected light propagates along a different redirected axis. An output surface of the light redirecting member receives the redirected light and transmits the redirected light as output light propagating along an output axis and exiting the light redirecting member. A curved intersection of the curved reflective surface and a first plane formed by the input and redirected axes has a radius of curvature. The curved reflective surface has an axis of revolution disposed in the first plane. The axis of revolution forms a first angle with the redirected axis which is non-zero. The waveguide alignment member is configured such that the end face of the optical wave guide is positioned at a location that is not a geometric focus of the curved reflective surface.

Embodiments of a pre-mold assembly for a distribution cable having one or more tether cables are provided. The assembly includes a first shell having a first inner surface and a first outer surface, a second shell having a second inner surface and a second outer surface, and a clip that couples the first shell to the second shell. The clip has a first leg configured to engage the first outer surface of the first shell and a second leg configured to engage the second outer surface of the second shell. In an assembled state, the inner surfaces of the shells define a first channel configured to hold the distribution cable. Further, the inner surfaces of the shells define a second channel that originates within the shells. The second channel is angled relative to the first channel and is configured to hold the one or more tether cables.

An optical fiber is contacted by a first guide part on the inside of a bend. The first guide part is disposed apart from a region of a fixing member from which the optical fiber is drawn out. Specifically, a first non-contact part in which the optical fiber does not contact a guide member is provided between the first guide part and the drawn out part of the optical fiber from the fixing member. The optical fiber also contacts a second guide part on the outside of the bend. The second guide part is disposed apart from the first guide part, and a second non-contact part in which the optical fiber does not contact the guide member is also provided between the first guide part and the second guide part.

The disclosure describes a method for assembling an optical coupler, the method may include (a) inserting optical fibers of an array of optical fibers through an array of openings of a mount of the optical coupler so that tips of the optical fibers pass through the array of openings of the mount and reach an adaptor; wherein the array of openings of the mount exhibit a first positioning accuracy; (b) using the adaptor to position the tips of the optical fibers at predefined locations, at a second positioning accuracy that is higher than the first positioning accuracy; (c) fixing the tips of the optical fibers to the mount while maintaining the tips of the optical fibers at the predefined locations; and (d) detaching the mount from the adaptor.

In an L-angle type optical connector for bending an optical fiber in a right angle direction in wiring, an L-angle member which accommodates a bent portion, which is bent in a right angle direction, of the optical fiber has a cut-out spanning the entire length of the L-angle member along the inside of the bent portion, and a protrusion is formed on inner side surfaces, which sandwich the cut-out, of the L-angle member in a protruded manner. The member which accommodates the bent portion, which is bent in a right angle direction, of the optical fiber is constituted of one component.

An optical connector includes a first attachment area for receiving and permanently attaching to an optical waveguide. A light coupling unit is disposed and configured to move translationally and not rotationally within the housing of the connector. The light coupling unit includes a second attachment area for receiving and permanently attaching to an optical waveguide received and permanently attached at the first attachment area. The light coupling unit also includes light redirecting surface. The light redirecting surface is configured such that when an optical waveguide is received and permanently attached at the first and second attachment areas, the light redirecting surface receives and redirects light from the optical waveguide. The optical waveguide limits, but does not prevent, a movement of the light coupling unit within the housing.

Each optical cable includes an array of at least one optical waveguide and at least one optical ferrule attached to the array of optical waveguides. The housing includes a first housing portion and a second housing portion engaged with the first housing portion. The second housing portion comprises at least one carrier and one frame. The carrier and frame of the second housing portion are configured to support the one or more optical cables. The first housing portion and the second housing portion are configured such that mechanical engagement of the first housing portion with the second housing portion moves the carrier relative to the frame. Movement of the carrier relative to the frame causes a bend in each optical waveguide and rotation of each ferrule. The bend provides a predetermined spring force of the optical waveguides at a predetermined angle of the ferrule.

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.
