Abstract

The soliton format has important advantages (long-haul transmission, stability, high bit rates) but also some inherent limitations, such as soliton interaction[1], that can cause practical problems and limit the bit rate. To minimise soliton interaction, several techniques such as amplitude shifts [2] and phase shifts [3] have been suggested during the last few years. In this paper, we propose a novel method for soliton interaction control in which selective solitons of a bit sequence are frequency shifted. It is shown that this technique can significantly increase the collision distance.
