る光フアイバデータリンク。 In an optical fiber data link comprising an optical receiver that converts and outputs a received optical signal as an output signal, an optical transmitter that transmits the optical signal, and a power supply to the optical receiver and the optical transmitter, If the transition detection means detects the transition of the output signal and the transition detection time interval detected by the transition detection means exceeds a waiting time determined by a predetermined condition, the power supply to the optical transmitter is turned off during the period exceeding the waiting time. An optical fiber data link comprising a power supply cutoff means for cutting off the power supply.
