<p>The present invention relates to a light transmission module (1) with a light transmission processing unit (2) including a light emitting portion (23) for outputting an optical signal corresponding to a data signal input as an electrical signal and a power supply controller (25) for controlling a drive power supply of the light emitting portion (23); a light transmission path (4) for transmitting the optical signal introduced from the light transmission processing unit (2); and a light reception processing unit (3) with a light receiving portion (31) for receiving the optical signal output from the light transmission path (4) and outputting an electrical signal corresponding to the optical signal and a power supply controller (34) for controlling a drive power supply of the light receiving portion (31); the light transmission module further including at least one electrical transmission path (5), connecting the light transmission processing unit (2) and the light reception processing unit (3), for transmitting a control signal for controlling power supply to the light emitting portion (23) and the light receiving portion (31) to the power supply controllers (25, 34); wherein the power supply controllers (25, 34) control the power supply to the light emitting portion (23) and the light receiving portion (31) based on the control signal input via the electrical transmission path (5). The light transmission module capable of reducing the power consumption in time of standby with a simple configuration is thus provided.</p> |
