20 Gb/s optical soliton transmission is demonstrated over 70 km. Highly efficient distributed Raman amplifiers for fiber-loss compensation are realized by using high An dispersion-shifted singlemode fibers pumped by laser-diodes. To achieve the highest bit rate transmission, optical multiplexing and demultiplexing techniques are also employed. We measure the bit error rate (BER) performance dependency on the input peak power of optical pulse. At the input peak power required for transmitting optical solitons, no power penalty can be seen, while the BER performance degrades when decreasing the input peak power.
