Abstract:
A dispersion compensation system for an optical system comprising:an optical signal generator for providing an optical signal capable of being transmitted via a fiber optic link in an optical network, said optical signal characterized as having an operating center wavelength and said fiber optic length exhibiting means for causing polarization mode dispersion of said optical signal; a detector device for detecting an amount of polarization mode dispersion characteristic of said optical signal transmitted in said fiber link and generating an electric signal representing said detected amount; wavelength-locked loop servo-control circuit for automatically adjusting a peaked center wavelength of said optical signal in accordance with said detected amount of polarization mode dispersion to thereby minimize said polarization mode dispersion of said optical signal in said optical fiber link, said adjusted optical signal capable of being optimally transmitted over longer fiber distances with reduced dispersion effects in said optical network.
