“…We consider in this contribution the specific case of DOF whose parameters are inspired by the previous numerical works which were carried out in the context of the transmission of high-speed telecommunication signals in dense dispersion managed links [15]. The fabrication of such a DOF is fully consistent with existing drawing techniques [16]. More precisely, the stepwise dispersion profile over one spatial period K of the fiber under study is provided by the map…”

a b s t r a c tWe analyze the modulation instability spectrum in a varying dispersion optical fiber as a function of the dispersion oscillation amplitude. For large dispersion oscillations, we predict a novel sideband splitting into different sub-sidebands. The emergence of the new sidebands is observed whenever the classical perturbation analysis for parametric resonances predicts vanishing sideband amplitudes. The numerical results are in good quantitative agreement with Floquet or Bloch stability analysis of four-wave mixing in the periodic dispersion fiber. We have also shown that linear gain or loss may have a dramatic influence in reshaping the new sidebands.

“…[17], [27]- [28], dispersion of fiber sections can fluctuate along the line due to the extreme sensitivity of the DDM fiber drawing process or simply because of the influence of surroundings [27]- [28] and thus could lead to pulse broadening and signal degradations [29]- [30]. …”

“…[14], it seems technically difficult during the drawing process to achieve a slope management by means of opposite slope fiber sections. Consequently, manufacturers would often prefer to minimize a fixed value of the line dispersion slope [17]- [18].…”

“…In 2003, Fatome et al have also demonstrated the potential of the DDM technique for 160-Gbit/s applications through the propagation of a 160-GHz pulse train on 900 km in a commercially available NZ-DSF fiber based dispersion map [13]. In parallel, dense dispersion fibers called "perfect cables" because of their spliceless feature were also developed to overcome the practical implementation issue provided by the concatenation of a large number of fiber sections and in particular the resulting splicing losses [14], [17]- [18]. The drawing process of this kind of DDM fibers was demonstrated in refs.…”

“…The drawing process of this kind of DDM fibers was demonstrated in refs. [14], [17]- [18] and lead to the first and only experimental system result of a 100-Gbit/s transmission on 1000 km [14]. More recently, a comparison between the DDM and quasi-linear regimes at 160 Gbit/s has been also reported in ref.…”
