We propose long-term storage of a soliton bit stream in a fiber ring in which loss is compensated by phase-sensitive amplification. We show that the 1’s (soliton pulses) are asymptotically stable and that the noise on the 0’s of the bit stream (absence of a soliton) is bounded. Moreover, the soliton–soliton interaction is efficiently suppressed by the phase-sensitive amplifiers.
