Description of the invention (2) Materials and plastic injection molding technology have become the mainstream of manufacturing due to lower costs, including US patent US 5, 631,991 "PLASTIC OPTICAL SUBASSEMBLIES FOR LIGHT TRANSFER BETWEEN AN OPTICAL FIBER AND AN 0PT0ELECTRIC CONVERTER AND THE FABRICATION OF SUCH PLASTIC OPTICAL SUBASSEMBLIES "; or US 6,432, 73 3 B1 r METHOD FOR PRODUCING AN OPTICAL MODULE", and US 6, 302, 596B1 "SMALL FORM FACTOR OPTOELECTRIC TRANSCEIVERS", as shown in the first picture However, the above-mentioned conventional technology (taking the first picture as an example) has the following problems or disadvantages during manufacture: [1], the outer casing A2 of the optical sub-module A1 is integrally injection-molded into a "one-piece type" The structure has a hole A3 at one end for assembling optical fibers, and a hole A4 at the other end for assembling functional components, and a lens A5 is provided between the holes A3 and A4, and the lens A5 can be connected to the housing Body A2—The body is shaped as shown in the first figure, but it can also be non-integrated as shown in US 5,631,991 or US .6, 43 2, 733 B1; It is difficult to set up and it is difficult to control the molding quality of the injection molded body, especially the quality of the lens surface A6 of the lens A5 in the first picture, which easily affects the quality of the finished optical sub-module A1 and reduces the yield. Increasing the hassle of calibration or assembly operations relatively increases costs. [2] The conventional detection method of the optical sub-module A1 generally adjusts the position of the functional element by the optical fiber coupling efficiency; that is, when the functional element is to be assembled on the outer casing, the optical fiber has been set in the hole A3 Inside, the detection device is used by the fiber end to adjust the position of the functional components by the fiber coupling efficiency

"[3] Moreover, the above-mentioned conventional detection methods for adjusting the position of functional components by using optical fiber coupling efficiency have many potentials that can affect the detection results, because, for example, there are certain tolerances in the quality of optical fibers. And the quality of the functional components is not fixed (such as the emission power of the laser diode, which is non-constant ^ · 'The error in the quality of the T0SA finished product is easy to cause, try to illustrate it. The finished product is completely based on the transmission power of the functional components used at the time of the alignment and alignment operations or the quality specifications of the S 70 optical fiber, that is, it is possible to test the qualified quality of qualified ports in a conventional manner. For the functional components or optical fibers used at the time ⑽ L · If it is easy to use, if the user inserts other optical fibers, because of the effect ^ the used optical fiber has an error range, and may be of poor quality ^ later ' Therefore, the quality of the finished product cannot be accurately grasped, so that the yield rate cannot be improved, and the improvement occurs.
