Dynamic dispersion compensation in high-speed optical transmission systems

摘要

In a system and method for dynamic compensation, one or more spectral components within the electrical spectrum of the received data signals is used for adjusting the dispersion of the received signals to provide a dispersion-compensated signal. In one example, the amplitude of the tone of the transmission bit rate of the received signals is determined and employed as the primary spectral component used for the compensation process. The amplitude of the tone of the transmission bit rate is directly related to dispersion, and therefore, the dispersion compensation process is not adversely impacted by other unrelated variables in the communication system, and accurate dispersion compensation is achieved.
