ABSTRACT:
It is the object of the invention to provide a WDM optical transmitter, in which levels of optical signals transmitted therefrom is increased and equalized. Optical amplifiers, which are provided with rare metal doped optical fibers and laser diodes for pumping them, are respectively connected with the output ports of light sources. The gains of the optical fiber amplifiers are so controlled that levels of the optical signals at the output port of a coupler, which multiplexes the output powers of the optical fiber amplifiers, are equalized.
