摘要： An optical connecting member realizes an optical connecting between a multi-core fiber and a plurality of single-core fibers by a waveguide part which connects a first end face and a second end face. With the optical connecting member, a connected end which is connected to the first end face is a straight-line portion that is orthogonal to the first end face in each of the plurality of waveguide parts. In addition, a diverged end which is diverged to the second end face is a straight-line portion that is orthogonal to the second end face. Consequently, light that has passed through the waveguide parts is emitted from the first end face and the second end face substantially perpendicularly to the faces, thereby enabling optical connecting loss to be favorably inhibited.

摘要： Disclosed is an optical connector, the optical connector being one of a pair of optical connectors connected to face each other along a first direction. This optical connector comprises a ferrule that holds an optical fiber, the ferrule exposing an end surface of the optical fiber from a ferrule end surface closer to the other optical connector in the first direction, and a ferrule cap that covers the ferrule. The ferrule cap has a light transmission portion through which a light path extending from the end surface of the optical fiber is made to pass. An end of the ferrule cap except for the light transmission portion is positioned closer to the other optical connector with respect to the end surface of the optical fiber and the light transmission portion in the first direction.
