    摘要: An optical transmitter includes a laser diode module including a laser diode which outputs a light signal to a transmission line, a driving unit which drives the laser diode in accordance with an input signal indicative of data to be transmitted, and a coupling unit for connecting an output of the driving unit to an input of the laser diode module. The coupling unit allows an alternating current to flow through the laser diode and inhibits the output of the driving unit from being subjected to a direct current from the laser diode module.
