Abstract
The present disclosure relates to a WDM-PON optical transmitter; and, more particularly, to a system for controlling a driving current of the WDM-PON optical transmitter. The present disclosure provides a driving current control system of an optical transmitter for use in WDM-PON including a plurality of optical transmitters, each transmitter generating and transmitting a transmittance optical signal based on a driving current and an optical multiplexer/demultiplexer for combining the optical signals received from the plurality of the optical transmitters to output a combined optical signal through a single common terminal, wherein the driving current is controlled based on the combined optical signal outputted from the common terminal.
