摘要： A sleeve (21) includes a core (22) of transparent synthetic resin and a cladding (23), also of transparent synthetic resin, having a smaller refractive index than the core. The core includes an optical waveguide (24) extending in an optical axial direction to taper in a conical shape and a lens (27) formed at the large diameter end of the waveguide. The lens receives light and converges it. There is a circular flange-like guide integral to the outer wall in the vicinity of the lens. The cladding (23) is formed concentrically with the core in intimate contact with the outer wall of the core. The configuration improves the transmission efficiency of light and contributes to cost reduction of the sleeve.

摘要： A light emitting and receiving device consists of a light propagating member provided with a light emitting means for converting first electrical signals into first optical signals, and a light receiving means for receiving and converting second optical signals into second electrical signals. The light receiving means is disposed coaxially with an optical fiber. The light propagating member is situated between the optical fiber and the light receiving means. The light emitting means emits the first optical signals into the optical fiber, and the light propagating member receives from the optical fiber and propagates therethrough the second optical signals to the light receiving means. Loss of optical power is suppressed, and a downsized light emitting and receiving device is attained.

摘要： A ferule structure for receiving an optical fiber composed of a core and a sheathing for covering the core exclusive of its end includes a core holder for holding the core; a sheath holder for holding the sheathing, communicating with the core holder and being located on an outer wall of the sheathing; and a metallic cylinder member for fixing the sheathing. The metallic member is formed integrally to the sheathing holder. The sheathing holder has a window from which the metallic cylinder member is partially exposed. The metallic cylinder member is caulked through the window so that the sheathing is compressed toward the core. In this configuration, the optical fiber and ferule can be surely secured to each other without using an adhesive.
