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： In a triangular-sectioned prism 11 having a first plane 11a opposite an end face of an optical fiber 12, a second plane 11b opposite a light receiving element 13 and a third plane 11c which reflects received light 21 incident thereon from the optical fiber 12 toward the second plane 11b and transmits transmission light 22 emitted from a light emitting element toward the first plane 11a, a cylindrical member 32 of a refractive index larger than that of the prism 11 is embedded in that area of the prism 11 which is opposite the end face of the optical fiber 12. The cylindrical member 32 effectively suppresses the leakage therefrom of light, providing increased optical coupling efficiency as compared with that achievable by use of a mere prism structure.

摘要： An optical guide 43 is partly buried in a lens 43 on the diameter of its aperture, the lens 43 converging received light incident from the end face of an optical fiber onto a light receiving element 15 and the optical conductor 33 having a refractive index larger than that of the lens 43. The optical guide 33 is composed of a buried portion 33-1 and an extending portion 33-2, and transmitting light 22 incident on the optical guide 33 from the end face 33c of the extending portion 33-2 is reflected by a reflecting surface 33a and launched into the optical fiber. The transmitting light 22 is guided by the optical guide 33 to the end face of the optical fiber without leakage to the receiving-side portion.

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.

摘要： An optical connector to be connected to an optical plug holding optical fibers includes: a light-emitting element; a light-receiving element; and sleeves that optically connect the light-emitting element and the light-receiving element to optical fibers of the optical plug, respectively, in which a transmission sleeve and a reception sleeve are connected to each other via a link section to form a sleeve unit. The sleeve unit is secured by press-fitting the link section into a connector body. A stress caused by the press fitting is not exerted to the transmission sleeve and the reception sleeve, so that the optical functions (optical properties) of the sleeves can be prevented from being compromised by the stress.
