摘要： This invention provides an optical transmitter in which reduced power consumption is achieved by, when a signal generator needs data transmission, driving a laser emitting device to perform emission. An optical transmitter includes a receiver, a laser driving circuit, a light emitting unit constituted by a plurality of laser emitting devices, and an EDID memory. The receiver and the laser driving circuit are supplied with power from a dedicated external power supply through a power-supply line, and the power-supply line is provided with a switch. The contact of the switch is controlled to open and close based on a power-supply voltage supplied from the DDC controller to the EDID memory.
