Measurement of ultralow Gordon-Haus timing jitter in dispersion-managed soliton systems

We measure, for the first time, the growth of the Gordon-Haus timing jitter in dispersion-managed soliton communication systems without inline soliton control. After 650-km transmission with a relatively high average dispersion of 0.87 ps/nm/km and a pulsewidth of 14 ps, compatible with 20 Gb/s, we measure a very low timing jitter of 45 fs. Hence, medium range dispersion-managed soliton transmission systems have, in general, a good margin toward Gordon-Haus timing jitter.
