摘要： Attachments are respectively attached to one ends of a pair of light guides, which are integrally formed via a connecting portion, such that the attachments surround the one ends of the light guides. The one ends protrude from a rear face of a receptacle body and are opposed to a light-emitting device and a light-receiving device, respectively. The attachments are inserted and positioned in guide holes formed respectively on the light-emitting device and the light-receiving device, and the optical axes of the pair of light guides and the optical axes of the light-emitting device and the light-receiving device are aligned with each other.

摘要： The object of the present invention is to suppress a decrease in the optical function of a sleeve by ensuring that a liquid chemical substance is not apt to remain on a peripheral surface of the sleeve even when the liquid chemical substance enters a connector. The present invention relates to an optical connector which is connected to an optical plug holding an optical fiber to a terminal end of which a ferrule is attached. The optical connector of the present invention has a guide pipe into which a ferrule is inserted and on an inner circumferential surface of which a supporting portion (a convexity) is formed, a light-emitting device, a light-receiving device, and a sleeve which is positioned by the supporting portion and optically connects the light-emitting device, the light-receiving device and the optical fiber. According to the present invention, there is a space between the guide pipe and the sleeve and, therefore, the phenomenon that a chemical substance adheres to a wide area and remains does not occur.

摘要： A prism 11 is formed which has a first face 11a opposing an end face of an optical fiber 21 and receiving a light-to-be-received from the optical fiber, second and third faces 11b and 11c adjoining opposite ends of the first face 11a at right angles and opposing each other, a fourth face 11d for reflecting the light-to-be-received from the face 11a toward the face 11b, and a fifth face 11e reflecting a light-to-be-transmitted as projected from a light source through the face 11c toward the face 11a. First and second light-to-be-received converging lenses 12 and 13 are disposed on the faces 11a and 11b of the prism 11 and first and second light-to-be-transmitted converging lenses 14 and 15 are disposed on the faces 11a and 11c. The tilt angles β1 and β2 of the faces 11d and 11e with respect to the optical fiber axis 21a are less than 45°. With this configuration, if the light-to-be-received enters the light-receiving element 22 and the light-emitting element 23 and is reflected by these elements, such reflected light is prevented from returning back into the optical fiber whereby occurrence of far-end crosstalk can be suppressed.
