Abstract
An optical connector assembly has a female connector having a recess formed in its front surface, and a male connector having a cavity and having a projection formed on its front surface which is partly or entirely deformable so that the tip of an optical fiber supported by the projection will ensuredly be fitted into the innermost portion of the recess. Incoming/outgoing beam surfaces at the innermost part of the recess and at the tip of the projection are defined by the end faces of optical fibers extending through the female and male connectors. A collimater lens may be provided on the end face of each optical fiber for enlarging the diameter of transmitted beams and for deflecting the beams in parallel, so that transmission loss caused by dust in the water is kept to a minimum level. A device for forming jet streams is provided at the joint surfaces of the male and female connectors which serves to jet water or a detergent stored in a storage chamber to the end faces of both optical fibers and to blow away dust, when the connectors are connected, thereby reducing the transmission loss caused by the dust.
