Abstract
An optical transmitter with a plurality of transmitter units each providing a Peltier device is disclosed. The Peltier devices of the invention are connected in series with respect to the driver, accordingly, even when the Peltier devices show a relative low impedance, a total load impedance viewed from the driver becomes a substantial value and the total power consumption of the transmitter may be reduced.
