PROBLEM TO BE SOLVED: To enable high-quality and high-speed long-distance transmission of parallel digital signals such as video, audio, and control signals, and in particular, control digital signals such as video, audio, and control that are transmitted in both directions. At the same time, it is intended to enable transmission through a single optical fiber. A source side unit 1 including a source side electrical signal processing unit 4 and a photoelectric conversion unit, a sink side unit 2 including a sink side electrical signal processing unit 5 and a photoelectric conversion unit, and including a control signal. This is a parallel digital signal bidirectional transmission device that converts a parallel digital signal into a serial signal via a single optical fiber 3. [Selection] Figure 1 |
