  • Technique for reducing distortion characteristics in fiber-optic links
    Patent number: 4893300
    Abstract: The present invention relates to a technique for suppressing intermodulation products introduced by nonlinearities of a laser in a multicarrier Freqeuncy Division Multiplexed (FDM) fiberoptic link. More particularly, for two or more closely spaced FDM channel information signals within a predetermined band of frequencies in an FDM optical transmission system, third-order intermodulation products, which are produced by nonlinearities of a transmitting laser, also fall in-band and provide interference in the channel information signals.
