Experimental Demonstration of Massive WDM Overtransoceanic Distances Using Dispersion Managed Solitons

Localized Waves in Optical Systems with Periodic Dispersion and Nonlinearity Management

“…An interesting modification of the classical soliton occurs in optical signal transmission along dispersion-managed (DM) links. In fibre optic communications, a periodic dispersion management-alternation of the fibre spans with positive and negative linear dispersionis an established technique to improve system performance and has been used to achieve ultra-long haul transmission systems [22]. Optical pulses propagating in a DM system experience a periodic change of their key parameters such as pulse width, power, and the phase parameter (chirp), following the periodic variations of the dispersion.…”

“…The change in the sign of dispersion causes these socalled DM solitons to temporally broaden and recompress or "breathe" as they propagate. The prevalence of DM solitons has generated intensive study toward understanding their behaviour (see, e.g., [21,22,).…”

Dispersion-managed soliton in optical fibers with zero average dispersion

“…3,9,10 ). Note that choice of βs ≫ 1 for zero iteration results in convergence of iteration sequence (7) to Gaussian-like solution with β is given by (9). It can indicate that solution of (3) for βs ≫ 1 also converges for large z to that Gaussian-like solution.…”

“…Dispersion-managed (DM) system 1 , which is the system with periodical variation of dispersion along optical fiber, is one of the key point of current development of ultrafast high-bit-rate optical communication lines [2][3][4][5][6][7] . The main factor limiting the bit-rate capacity is pulsebroadening due to the chromatic dispersion of the optical fiber which can be overcome by periodical changing of sigh of fiber's dispersion to create very low (or even zero) path-average dispersion.…”

“…For larger scales | t| > ∼ 1.3 the correct presentation of DM soliton requires a lot of terms of series expansion. Instead one can get asymptotical behavior from (7). E.g.…”
