Abstract :
A 35 km long distributed erbium fibre preamplifier has been used to provide dispersion equalisation and to maintain the signal above the receiver sensitivity level. Remote supply of pump power to the input of the lightly-doped fibre provides significant improvement in amplifier performance.
