Abstract
A plug-type optical connector is provided with a ferrule and an aligning sleeve member. The aligning sleeve member receives a portion of the ferrule including an abutting end face inside a bore to prevent staining and damage and uses a movable shutter to prevent light emitted through the ferrule from leaking to the outside. The socket type optical connector is provided with a ferrule and a holding section. The optical connector is not provided with an aligning sleeve member and further can hold a coated optical fiber by a holding section behind the ferrule by a radius of curvature of at least a prescribed minimum radius of curvature. Optical loss in the coated optical fiber can be reduced while effectively reducing the external dimensions in the direction of extension of the ferrule at the time of use. An optical fiber connecting device that includes a combination of a pair of optical connectors is also provided to be suitably applied to an optical transmission line laid indoors.
