Optical waveguide module and method of producing such module

摘要

The present invention provides an optical waveguide module in which, under the high temperature and high humidity, degradation of characteristics does not occur and which has strength against oscillation, a simple structure, and high reliability. The 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 1x4 branch optical waveguide by an adhesive having light transmission properties. The module unit (30) is provided in a housing (10). Liquid resin is poured into the housing and at least a connecting portion between the optical waveguide and the optical fiber cable is covered with resin contained in the housing (10). The housing (10) is sealed with a cover unit, 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.
