    Abstract: An endoscope system includes: an image sensor, a first photoelectric sensor configured to convert an imaging signal and test data output from the image sensor into an optical signal and output the optical signal, optical fibers configured to transmit the optical signal output from the first photoelectric sensor, and an information processing device. The information processing device includes a second photoelectric sensor configured to receive the optical signal transmitted through the optical fibers, and is configured to: measure a current value corresponding to a receiving sensitivity of the test data converted into an electric signal by the second photoelectric sensor; measure a bit error rate of the test data; determine a transmission level of the test data based on the current value and the bit error rate; and assume reasons for a decrease in the transmission level and cause the transmission level to recover based on the transmission level.

    Abstract: An endoscope system includes: an image sensor; a transmission module; a first optical fiber; a first optical connector; a second optical connector; a communication mode stabilizing unit configured to smooth an optical beam; a second optical fiber having a core diameter larger than a core diameter of the first optical fiber; a reception module; a first correction optical system including a first lens and configured to increase a beam diameter of an optical signal output from an end of the first optical fiber, and a second lens configured to convert the optical signal whose beam diameter is increased by the first lens into parallel light; and a second correction optical system. The second optical fiber is a step index optical fiber, and the communication mode stabilizing unit smoothes the optical beam by using a larger area of a core of the first optical fiber.
