Abstract
Abstract It is an object of the present invention to provide an optical waveguide module in which, under the high temperature and high humidity, degradation of characteristics does not occur and which has strength to the oscillation, simple structure, and high reliability. A module unit 30 is formed by bonding a connector 32 provided at one end of a single-optical fiber cable 22 and a connector 31 provided at one end of a ribbon optical fiber cable 21 at both ends of a waveguide substrate 35 having a 1×4 branch optical waveguide by an adhesive having light transmission properties. The module unit 30 is provided in a housing 10, and at least a connecting portion between the optical waveguide and the optical fiber cable is covered with the resin contained in the housing 10. The housing 10 is sealed with a cover unit 15, and the single-optical fiber cable 22 and the ribbon optical fiber cable 21 are tightly inserted into a respective hole at end walls of the housing 10 and led out to the outside.
