Abstract
A device for automatically regulating the output power of a transmitter module in an optical-fiber transmission system comprises a first circuit connected between a temperature sensor and the laser diode in order to regulate the direct current of the laser diode, and a second circuit connected between a photodiode and the laser diode in order to regulate the laser-diode modulation current.
