5 Gb/s optical soliton transmission over a 23 km amplification spacing is successfully demonstrated using a gain-switched 1.55 μm distributed feedback laser diode and Ti:LiNbO3 intensity modulator. An Er3+ -doped fiber amplifier, pumped by 1.45 and 1.48 μm laser diodes, is employed for achieving intense optical pulses. Transmission fiber-loss is completely compensated for by Raman amplification using by 1.45 and 1.48 μm laser-diodes pumping. The bit error rate (BER) is measured, and BER of 2 x 10-10 is achieved.
