Abstract

PURPOSE:To enhance the reliability of optical transmission by permanently coupling an optical fiber cable to a light receiving and emitting element with a resin mold. CONSTITUTION:Optical fibers 1 and a protective layer 2 are permanently coupled to a light receiving and emitting element 5 by fixing with a resin mold 4 having a built-in photo/electric signal converter 6. Since the connection and disconnection of the optical fibers are carried out with an electric connector 7, the penetration of dust into the photo signal path and the damage of the ends of the optical fibers are prevented, so the reliability of optical transmission can be enhanced.

構造の光ファイバ伝送モジュールは。According to the optical fiber transmission module with this structure,
It is suitable for signal transmission in places with strong electrical noise and electromagnetic induction, or between electronic devices with a high potential difference. However, since the optical connector section is designed to be detachable, there is a risk that dust may adhere to the end face of the optical fiber or the end face of the optical fiber may be damaged if the optical connector is handled while the optical connector is removed. Further, as the optical connector is repeatedly attached and detached, play may occur, and the optical axis of the optical fiber and the optical axis of the light receiving/emitting element may become misaligned. Thus, an optical fiber transmission module with such a structure.
