モジユール。[Claims for Utility Model Registration] (1) The product is made into a cylinder whose interior is separated into an optical fiber plug insertion chamber and a photoelectric element storage chamber by a partition plate;
and a receptacle provided with an optical fiber insertion hole into which a protruding optical fiber of an optical fiber plug externally coupled to the partition plate is inserted, and a light emitting element or a light receiving element housed in the photoelectric element storage chamber of this receptacle. In an optical transmission module comprising a photoelectric element incorporating a photoelectric conversion integrated circuit and a cover fitted into the receptacle from behind the photoelectric element, the photoelectric element storage chamber has an inner diameter larger than an outer diameter of the photoelectric element. 2 orthogonal to each other on the inner diameter side surface.
A plane is set as a reference plane, the optical fiber insertion hole is provided at a position a predetermined distance from this reference plane, and the photoelectric element with two orthogonal outer diameter sides as a reference presses the reference planes together. An optical transmission module, wherein the photoelectric element is housed in the photoelectric element storage chamber, and a pressing member is press-fitted into the gap between the two to hold the photoelectric element. (2) The optical transmission module according to claim 1, wherein the pressing member and the cover are integrated. (3) The optical transmission module according to claim 1, wherein the coefficient of thermal expansion of the pressing member is set to be equal to or higher than the coefficient of thermal expansion of the receptacle.
