TIMING-JITTER REDUCTION FOR A DISPERSION-MANAGED SOLITON SYSTEM - EXPERIMENTAL-EVIDENCE

We have measured the timing jitter for dispersion-managed solitons in a recirculating loop for distances up to 20,000 km. The data were obta ined with modulated data, 2(7) - 1 and 2(23) - 1 pseudorandom binary s equence patterns, at 10-Gbit/s rates and with an unmodulated pulse tra in at 10 GHz. We have obtained good agreement with our data, using a f iltered Gordon-Haus model for the timing jitter reduced by the energy enhancement of our solitons relative to solitons in a fiber with a con stant dispersion equal to our map's path-average dispersion. We have a lso measured a bit-error rate of <10(-9) at a distance of 15,000 km. ( C) 1997 Optical Society of America.
