WAVELENGTH DIVISION MULTIPLEXING OPTICAL TRANSMITTER AND OPERATING METHOD FOR THE SAME

摘要

According to an embodiment of the present invention, a wavelength division multiplexing (WDM) optical transmitter includes first to n^th optical transmitters which output first to n^th optical signals having different wavelengths; a wavelength multiplexer which generates an output optical signal by multiplexing the first to n^th optical signals; a tap coupler which receives the output optical signal, and which generates an optical signal for control based on a part of the output optical signal; a light receiving device for control which receives the optical signal for control, and which outputs an optical current based on the optical signal for control; and a controller which separately controls the first to n^th optical transmitters based on the optical current, wherein the controller includes a look-up table, sequentially detects driving conditions of the first to n^th optical transmitters, and stores the detected driving conditions in the look-up table.
