| 摘要 |
An optical transceiver module for transmission or receipt of optical signals to and from an external optical path has a frame body having a structure for determining the position thereof relative to the external optical path, a substrate for mounting the optical elements thereon, and a light transmission window having a light guiding structure in light transmission direction in correspondence with the optical elements and the external optical path. The optical elements are formed so as to be sealed by the substrate, frame body, and light transmission window, and the frame body is formed so that the position thereof can be adjusted by fine moving the substrate and the light transmission window.
