摘要： An optical transmission apparatus includes a transmitter having a data write signal detection circuit for detecting a data write signal to output a parallel/serial conversion timing signal, a parallel/serial conversion circuit for converting parallel input data into serial data in response to the parallel/serial conversion timing signal, and a light-emitting element for converting the serial data output from the parallel/serial conversion circuit into an optical transmission signal, an optical fiber cable for transmitting the optical transmission signal supplied from the transmitter, and a receiver having a light-receiving element for converting the optical transmission signal supplied through the optical fiber cable into serial data, a serial/parallel conversion timing generation circuit for detecting a reception end timing of the serial data output from the receiver to output a serial/parallel conversion timing signal, a serial/parallel conversion circuit for converting serial data output from the receiver into parallel data in response to a serial/parallel conversion timing signal, and a delay circuit for delaying the serial/parallel conversion timing signal by a predetermined time period to reproduce and output the data write signal.
