Abstract

An inspection and assembly method of optic sub-module of the optical fiber transceiver are provided. The optic sub-module contains an outer housing that is a one-piece or two-piece structure and whose front side and back side have passing-through insertion holes installed for respectively assembling the function components and fibers. A lens is installed among the fibers and function components. The feature of this invention is: an image inspector is used to let the focus of the sampling lens be adjusted to co-plane with the fiber coupling plane while assembling the function components. Directly use the image that comes from the illuminating or receiving planes and shows on the coupling plane as the inspection objectives, and conduct the alignment positioning and fixing of the function components in the outer housing. Because the image calibration inspection of the illuminating or receiving planes is on the fiber coupling plane directly, the traditional technology shortcoming that comes from calibrating the position of the function components through the fiber coupling ratio after installing the fibers is prevented, and the transmission bandwidth of the fiber, especially multi-mode fiber is optimized. The function component could be the surface-emitting laser diode and includes caped TO-can packaged laser diode or SMT type (bare chip) laser diode. The fiber includes single-mode, multi-mode or plastic fibers. The yielding rate of finished products is raised and inspection operation is simplified to be good for mass-production.

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.
