Abstract
An optical fiber array according to the present invention comprises an optical coupling end face to be optically coupled to another optical line, and one ends of a plurality of optical fibers are arrayed in the optical coupling end face. The optical fiber array comprises a lower plate (3a) comprising a plurality of V-shaped grooves (4) for positioning the optical fibers exposing from one end of a ribbon part of the optical fibers, and an upper plate (3b) for pressing each optical fiber provided in each V-shaped groove (4) of the lower plate into the positioning groove. A boundary portion between the ribbon part (7) and the optical fibers (1) is fixed between the first and second plates (3a, 3b) by heat resistant adhesive (10), and the optical fibers from the boundary portion to a front end are fixed by solder (6) in an airtightness state. Accordingly, the hermetic sealing with sufficiently high airtightness can be achieved.
