Abstract

Recently, soliton transmission technology has matured considerably through the use of erbium-doped fiber amplifiers (EDFAs). They have been used to develop a new soliton communication method (Dynamic soliton or Guiding-center soliton) for sending solitons over long distances using lumped optical amp1ifiers.^1~3 This technique has a wide range of applicability from L_a (amplifier spacing) << Z_sp (soliton period) to L_a~Z_sp, depending on the maximum required transmission distance. In order to show that the soliton transmission technique has severa1 advantages over conventional IM/DD or coherent systems, it is very important to undertake a single-pass long-distance high speed soliton transmission experiment with pseudorandom signals, as has already been demonstrated in high speed linear systems with NRZ signals.^4~6 However, no study has been reported on the bit error rate (BER) of a 10 Gbit/s single-pass soliton system over 1000 km. In the present paper, we show for the first time that soliton data signals at 10 Gbit/s have been successfully transmitted over 1200 km using 24 EDFAs.
