Scaling guidelines of a soliton-based power limiter for 2R-optical regeneration applications

In this work, we report scaling rules for the design of all-fibered soliton-based power limiter for re-amplification and reshaping (2R) regeneration process. In particular, we propose general guidelines to fix the optimum fiber length and initial power of the regenerator. We have quantitatively pointed out the optical power limiting effect of the device enabling a significant reduction of the amplitude jitter of a degraded signal. Finally, realistic numerical simulations in the context of 160 Gbit/s signals show that an efficient improvement of signal quality could be achieved by means of such a device.
