ABSTRACT:
Timing jitter problems are effectively eliminated in a soliton transmission system realized by deploying a series of optical filters in groups whose group average center frequency intentionally differs from the group average center frequency of other optical filter groups. The center frequency of the series of optical filter groups is translated along the desired length of the system in a predetermined manner such as frequency increasing, frequency decreasing, and combinations of both. This creates a transmission environment which is substantially opaque to noise while remaining perfectly transparent to solitons. By arranging the optical filters in groups, it is possible to simplify the system design by reducing the number of filters having different nominal center frequencies.
