    Abstract: An optical signal transmission module is provided, in which a lens surface for condensing light emitted from an LD configured to convert an electrical signal to an optical signal and emit light of the optical signal is integrally formed on an end portion of an optical fiber, a mounting substrate for the LD to be mounted is configured with a specially-shaped substrate, and a fixing portion (a fixing hole portion) for the optical fiber to be fixed is integrally formed on the mounting substrate, at a position where the light emitted from the LD (the light of the optical signal) can be incident on the lens surface.

    Abstract: An endoscope includes: an insertion unit; an imaging unit to image a subject under examination and output an electrical image signal; a light modulation device to output an optical image signal based on the electrical image signal output from the imaging unit; a first light cable inserted in the insertion unit to transmit light emitted by a communication light source to the light modulation device; and a second light cable inserted in the insertion unit to transmit the optical image signal output from the light modulation device outside the insertion unit. The communication light source is different from an illumination light source emitting an illumination light for illuminating the subject under examination. The light modulation device modulates the light transmitted by the first light cable to generate the optical image signal.
