“…Following many earlier works [1]- [10], the model does not include losses and gain, presuming that they are mutually compensated at a smaller scale. The analysis presented below can be extended to include the losses and gain, but this is postponed to another work, as it is necessary first of all to understand properties of the conservative model.…”

A model of a long optical communication line consisting of alternating segments with anomalous and normal dispersion, whose lengths are picked up randomly from a certain interval, is considered. As the first stage of the analysis, we calculate small changes of parameters of a quasi-Gaussian pulse passing a double-segment cell by means of the variational approximation (VA) and approximate the evolution of the pulse passing many cells by smoothed ODEs with random coefficients, which are solved numerically. Next, we perform systematic direct simulations of the model. Results are presented as dependences of the pulse's mean width, and standard deviation of the width from its mean value, on 1 the propagation distance. Averaging over 200 different realizations of the random length set reveals slow long-scale dynamics of the pulse, frequently in the form of long-period oscillations of its width. It is thus found that the soliton is most stable in the case of the zero path-average dispersion (PAD), less stable in the case of anomalous PAD, and least stable in the case of normal PAD. The soliton's stability also strongly depends on its energy, the soliton with small energy being much more robust than its large-energy counterpart.

“…Traditionally, various methods of compensating fibre transmission impairments have been proposed, both in optical and electronic domain. Dispersion management was initially proposed to suppress the impact of fibre nonlinearity with minimal residual dispersion at the receiver-side [3,4], leading to strongly dispersion-managed links deployed across the commercial networks today [4]. With the advent of coherent systems, digital signal processing (DSP) has enabled electronic domain impairment compensation removing the need for low residual dispersion [5], electronic filtering allowing for significantly reduced guard bands between channels, and improved OSNR tolerance.…”

Abstract:We quantify the benefits of intra-channel nonlinear compensation in meshed optical networks, in view of network configuration, fibre design aspect, and dispersion management. We report that for a WDM optical transport network employing flexible 28Gbaud PMmQAM transponders with no in-line dispersion compensation, intrachannel nonlinear compensation, for PM-16QAM through traffic, offers significant improvements of up to 4dB in nonlinear tolerance (Q-factor) irrespective of the co-propagating modulation format, and that this benefit is further enhanced (1.5dB) by increasing local link dispersion. For dispersion managed links, we further report that advantages of intra-channel nonlinear compensation increase with in-line dispersion compensation ratio, with 1.5dB improvements after 95% in-line dispersion compensation, compared to uncompensated transmission.
