Fiber with ferrule, and optical module and method of manufacturing the same

摘要

The optical module comprises a ferrule, an optical fiber inserted into the ferrule, an optical communication functional unit for making the optical communication with the optical fiber, and a resin molded portion covering a part of the ferrule and the optical communication functional unit. The ferrule is provided with one or more concave grooves in a region exposed from the resin molded portion. Since this concave portion serves as a resin reservoir at the time of molding, the resin is prevented from adhering and covering on the outer surface of ferrule exposing from the resin molded portion.
