Abstract
In an optical fiber connector, the pair of optical fibers to be connected together are placed end-to-end in a linear groove which has been formed on a lateral surface of a central cylinder. They are held fixed by a holding member which is fitted in the groove and is moved towards the optical fibers according to the rotation of a hollow cylinder which externally touches the central cylinder, whereby the optical fibers can be connected with a precise alignment and accordingly with a low optical power loss.
