OPTICAL TRANSMITTER AND METHOD FOR CONTROLLING THE SAME

摘要

It is necessary to improve the signal quality of the optical signal emitted by a reconfigurable transmitter after a reconfiguration event, therefore, an optical transmitter according to an exemplary aspect of the invention includes a modulation means for modulating light by a driving signal with a reconfigurable format; a digital signal processing means for processing digital data to be transmitted by using parameters in order to generate the driving signal; and a control means for controlling the digital signal processing means by means of changing the parameters so as to keep the driving signal stable before and after changing the reconfigurable format.
