摘要： PROBLEM TO BE SOLVED: To provide a packaging method for fixing, on a base plate like a glass substrate, a filter module such as an optical multiplexer/demultiplexer used for an optical communication system including a multi-wavelength transmission system. SOLUTION: This is a packaging method of a filter module 30 to be fixed on a substrate 35 by applying a tensile force ≤50 gf to a port that is positioned diagonally in symmetry with the geometric or structural center of the filter module 30, in a package structure in which the filter module 30 with plural pairs of ports is fixed on the substrate 35. As a result, there is little increase in insertion loss of an optical signal, enabling a highly reliable product to be obtained. In addition, this application of the tensile force can suppress deformation of a resin adhesive part with a rod lens in the filter module 30, hopefully resulting in enhancement of the product yield.
