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 m with erbium ions. Numerical calculations are presented for a typical design example. It is seen that for a targeted ga

## lhe combined effects of upconversion and pump excited state absorption losses on the gain from co-and contmdirectwnallypumped erbium-doped fiber amplifiers have been studied qerimentully and simulated numerically. Our results indicate that for all fiber lengths, contradirectional gain is higher
