  • Patent number: 6632024
    Abstract: 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.
