This invention provides an optical fiber wiring board having excellent optical property, high reliability and high mounting property. This invention relates to an optical fiber component for connection having a substrate on which a plurality of optical fibers being wired, wherein a foam polymer layer is provided on a surface of the substrate wiring the optical fibers, or both on a surface of the substrate wiring the optical fibers and on a surface opposite to the surface of the substrate wiring the optical fibers, or so that whole of substrate is covered. The optical fiber component of the present invention may be further provided with a protective layer and may be filled with a filler. This invention provides also a manufacturing method of the optical fiber component for connection.

Optical fiber component for connection and manufacturing method thereof

An optical interconnection apparatus which is very easy to handle and does not cause excessive bending and breakage of the optical fibers when connecting with other optical apparatus is provided. The optical interconnection apparatus includes a base sheet and plural optical fibers two-dimensionally routed on the base sheet via an adhesive layer. The optical fibers form a routing pattern having at least a straight part, a crossing part, a curved part or a fiber pitch changing part. The apparatus further includes another base sheet this is adhered on the said routed optical fibers. The two base sheets have a different sizes so that one of the base sheets does not exist in the vicinity of the edge of the other base sheet at which the optical fibers are outwardly extended.

Optical interconnection apparatus

The present invention provides an optical interconnection apparatus free from attaching, fixing or adhering when come into contact with each other or with another material, and easy to handle. The optical interconnection apparatus according to the invention comprises a substrate (), a protective resin layer () composed of a silicone based rubber-like or gel-like material on one side or both sides of said substrate, and plural optical fibers () which are routed two-dimensionally routed on the substrate and provided at ends thereof with end portions () adapted to permit optical interconnections, and said optical fibers being held in place by said protective resin layer, wherein a non-tacky surface layer () is provided on the surface of said protective resin layer. The non-tacky surface layer is preferred to be composed of a silicone-based material and having a kinetic friction coefficient of 3.0 or less.

Optical connection component

Optical fiber wiring apparatus and optical fiber wiring method

An optical fiber ribbonizing apparatus is disclosed which arranges a plurality of optical fibers in parallel, applies a resin to peripheries of the plurality of optical fibers, and hardens the resin to form the optical fibers into a ribbon. The apparatus comprises a ribbonizing jig integrally including an optical fiber aligning mechanism for aligning the plurality of optical fibers in parallel, a resin applying mechanism for applying the resin to the optical fibers aligned by the fiber aligning mechanism and a resin hardening device for hardening the resin applied to the optical fibers by the resin applying mechanism, the optical fiber aligning mechanism, the resin applying mechanism and the resin hardening device being arranged in a line in an optical fiber inserting direction, and movement mechanism for moving at least one of the ribbonizing jig and the optical fibers in a predetermined direction relative to the other.

Optical fiber ribbonizing apparatus

An optical interconnection apparatus comprises an adhesive layer having a 2-dimensional plane, and optical fibers secured on the adhesive layer. The optical fibers are routed on the adhesive layer so as to have at least one of an intersection portion, a bent portion, and a changing portion of fiber pitch, and to have a end portion outwardly projecting from the adhesive layer. The projecting end portion is used for optical interconnection. At least a portion of the circumferential edge surface of the adhesive layer is covered by a flame resistant material at an end of the optical fiber and in the vicinity thereof.

This invention provides optical interconnection apparatus, which permit easy optical interconnections without a loss in the intactness of a routing pattern of optical fibers, and also their fabrication processes. An optical interconnection apparatus according to this invention has a base film having a two-dimensional plane, plural optical fibers routed on the base film an edge-dam arranged along or in a vicinity of a peripheral edge of the base film, a protective resin layer holding in place and protecting the plural optical fibers routed on the two-dimensional plane of the base film, and end portions located at opposite ends of the optical fibers and adapted to permit optical interconnections. The protective resin layer is formed, for example, by filling a resin material inside the edge-dam arranged along or in the vicinity of the peripheral edge of the base film and then solidifying it.

Optical interconnection apparatus and process for fabrication of the same

An optical interconnection apparatus ( ) comprises a two-dimensional flexible base film ( ), a plurality of optical fibers ( ) with end portion for optical connection (e.g., optical connectors), and a protective resin layer ( ) of plastic material filled inside edge-dam ( ) formed along or in the vicinity of the peripheral edges of the base film ( ). The base film ( ) has an opening, in which the protective resin layer ( ) covers the optical fibers ( ) to fix them. A plurality of such apparatus ( ) can be stacked to form a laminate. Since the base film ( ) has the opening where the optical fibers ( ) are routed intricately, the optical interconnection apparatus ( ) has improved flexibility and can be used in a narrow space.
