Soliton evolution in optical fibers and all-optical soliton recovery w
ith a nonlinear active loop mirror have been studied with view to appl
ications in transmission systems having a high bit-rate-distance produ
ct. A 1.3-ps pulse is successfully transmitted over 111 soliton period
s, reshaped, amplified, and transmitted another 111 soliton periods. (
