Abstract
An optical isolator module having a capillary 3 to which an optical fiber 2 has been fitted, an optical isolator 7 provided on the light-incident side of the capillary and a transparent member 8, and being set in a housing of a semiconductor module. The optical isolator module is provided on the side opposite to the light-incident side of the capillary, with a hermetic bead 11 which i) holds an optical fiber 2 which extends from the capillary in the direction opposite to its light-incident side and whose bare fiber stands uncovered by removing a resin coat, and ii) is fitted in a hermetically sealable state into an opening made in a housing side wall of the semiconductor module.
