ABSTRACT:
Timing jitter problems are effectively eliminated in a soliton transmission system realized in accordance with the principles of the present invention by deploying optical filters whose center frequency intentionally differs from the center frequency of adjacent optical filters. The center frequency of the series of optical filters is translated along the desired length of the system in a predetermined manner such as frequency increasing, frequency decreasing, and combinations of both to create a transmission environment which is substantially opaque to noise while remaining perfectly transparent to solitons.
