Abstract
In this work, we report scaling rules for the design of an all-fibered
soliton-based power limiter for reamplification and reshaping (2R)
regeneration process. In particular, we propose general guidelines to fix
the optimum fiber length and initial power of the regenerator. We
quantitatively point out the optical power limiting effect of the device
enabling a significant reduction of the amplitude jitter of a degraded
signal. Influence of the initial level of amplitude jitter is discussed and
the results are compared with a self-phase modulation-based configuration
working in the normal dispersion regime. Realistic numerical simulations in
the context of 160 Gbit/s signals confirm that an efficient improvement of
the signal quality can be achieved by means of such a device.
