32 GB/S OPTICAL SOLITON DATA-TRANSMISSION OVER 90 KM

We demonstrate error-free optical soliton transmission at 32 Gb/s over 90 km of dispersion-shifted fiber. Fiber loss was compensated for by using diode laser pumped Er3+-doped fiber amplifiers located every 30 km and a 4 Gb/s data pattern was passively multiplexed to 32 Gb/s. Approximately 16 ps wide, near transform-limited pulses were launched into the system and the output pulse width was about 14 ps. At the receiver, four-wave mixing was employed to perform all-optical demultiplexing of the data down to the base data rate. At a 10(-9) (2(15) - 1 word length) bit-error-rate, the penalties from the demultiplexing and the 90 km soliton transmission were approximately 1.6 and 0.5 dB, respectively.
