Abstract: An optical fiber assembly of the present invention is configured such that an optical fiber fixing section (i) is fixed to an SUS tube and (ii) sandwiches an optical fiber between a first member and a second member at an end part of the SUS tube, so that the optical fiber is fixed while being spaced from the SUS tube. This makes it possible to provide an optical fiber assembly having a structure that prevents an optical fiber from coming into contact with an edge part of a metal tube on the premise that the optical fiber is covered with the metal tube.

Abstract: An optical connector of an embodiment of the present invention includes a fixing member made up of two half sprit members engaged with each other, the fixing member applying external pressure, toward an optical fiber combining section of a spring push, to a protection tube which covers a stair part of an outer circumferential surface of the optical fiber combining section. The fixing member securely fixes the protection tube to the optical fiber combining section. As such, it is possible to provide a general-purpose optical connector having a high reliability that an optical fiber cord is unlikely to come off from the optical connector.
