Abstract:
A combination comprising:a photodetector;an optical fiber connector having at least two ferrules projecting outwardly therefrom and disposed in sidewardly spaced relationship from one another;a photoreceptacle positioned between and connecting said photodetector and said optical fiber connector, said photoreceptacle including:a transversely extending plate-shaped collar having a width dimension which is substantially smaller than the transversely-extending length dimension,an annular stepped part fixed to said collar and projecting outwardly from one side thereof in a direction toward said photodetector,an elongate hollow cylinder fixed to said collar and projecting outwardly from the other side thereof toward said optical fiber connector,an aperture extending through said hollow cylinder, said collar and said annular stepped part along a common axis,a hollow cylindrical elastic body secured to an inner surface of said hollow cylinder and having an opening therethrough which extends along the common axis, said elastic body being elongated axially over at least part of the length of said hollow cylinder;a holder positioned generally between said photodetector and said collar and mounted on said photodetector, said holder being disposed in surrounding relationship to said annular stepped part and having an opening therethrough into which said annular stepped part projects;one of said ferrules being inserted into said aperture so as to be disposed within the opening of said elastic body and pressingly engaged and supported by said elastic body, whereby said ferrule is permitted to pass light through said aperture to said photodetector; andthe remaining ferrule being positioned outside said hollow cylinder and projecting to a location disposed laterally outwardly from the width dimension of the collar so as to be free of contact with the photodetector.
