Abstract
A 20Gbit/s optical soliton transmission over 200 km has been successfully achieved for the first time by using multiple erbium-doped fibre repeaters. The erbium-doped amplifiers are used as lumped amplifiers. The repeater spacing is 25 km and the soliton pulse width is 20 ps. The erbium-doped fibre amplifiers are pumped by InGaAsP laser diodes.
