Abstract: A scheme for simultaneous compensation of dispersion and loss is proposed. It should be realizable by doping an optical fiber having a high negative dispersion coefficient at 1.55 mm with erbium ions. Numerical calculations are presented for a typical design example. It is seen that for a targeted gain of 15 dB there is an optimum doping level for which the required pump power is minimum and the noise figure is about 4 dB. Such an erbium-doped dispersion compensating fiber should be a promising alternative as a more compact unit than the combination of an erbium-doped fiber amplifier and dispersion compensating fiber as two individual components.
