  • Method of improving the electrical eye margin of an optical fiber transmission system having single mode and dispersion compensating fiber segments
    Patent number: 5677780
    Abstract: The self-phase modulation (SPM) effect in a dispersion compensating fiber (DCF) segment of an optical fiber transmission system is used to reduce the required length of the DCF segment needed to compensate the chromatic dispersion of a single mode fiber (SMF) segment of the system. It was determined that the length of the DCF segment at which the widest opening of the electrical eye diagram margin occurs, for a given optical input power to the DCF segment, decreases with increasing optical input power to the DCF segment. Increasing the optical input power to and reducing the length of the DCF segment thus both improves bit error rate of the system and reduces the cost for compensating for dispersion.
