Abstract
An optical fiber module includes: an optical transmission line having an optical fiber, a coating enclosing the optical fiber and a buffer layer enclosing the coating, apart of the optical fiber being exposed to outer side of a free end of the optical transmission line; and a fiber stub structure including a sleeve and a retainer section integrally forward extending from the sleeve as an integrated structure. The sleeve has a central hole for accommodating the optical transmission line. The retainer section has an inclined hole for accommodating a part of the optical fiber to make the direction of emergence of the light coaxial with the direction of incidence of the light of the light-emitting element. The fiber stub structure is an integrated structure, whereby the signal loss of incident light is reduced and the manufacturing cost is greatly lowered.
