Abstract-We have developed a model that accurately predicts the dynamics of the signal pulses and the growth of amplified spontaneous emission noise in a dispersion-managed soliton pulse train propagating in a recirculating fiber-loop experiment. Theoretically predicted dependencies of the amplitude and phase margins for the marks and the amplitude margin for the spaces as a function of distance are in remarkable agreement with the experiments. This model allows us to determine the key physical effects that limit the propagation distance in our experiments.Index Terms-Amplitude margin, amplified spontaneous emission noise, dispersion-managed soliton (DMS), excess gain, filter, phase margin, pulse dynamics, timing jitter.

“…(5) Models of this type are usually solved with periodic boundary conditions in . In order to prevent radiation (in those cases when it is generated) from re-entering the integration domain due to the periodicity, the linear equation ( 1) was solved directly by means of numerical methods in a broad integration interval zT, placing absorbers at its edges. In fact, the absorbers emulate a real physical effect, namely, the fact that the energy emitted with radiation is lost for the pulses.…”

We consider a long fiber-optic link consisting of alternating dispersive and nonlinear segments, i.e., a split-step model (SSM). Passage of a soliton through one cell of the link is described by an analytically derived map. Multiple numerical iterations of the map reveal that, at values of the system's stepsize (cell's size) L comparable to the pulse's dispersion length ZD, SSM supports stable propagation of pulses which almost exactly coincide with fundamental solitons of the corresponding averaged NLS equation. However, in contrast with the NLS equation, the SSM soliton is a strong attractor, i.e., a perturbed soliton rapidly relaxes to it, emitting some radiation. If the initial amplitude of the pulse is too small, it turns into a breather, and, below a certain threshold, it quickly decays into radiation. If L is essentially larger than ZD, the pulse rapidly rearranges itself into another one, with nearly the same area but essentially smaller energy. At L still larger, the pulse becomes unstable, with a complex system of stability windows found inside the unstable region. Moving solitons are generated by "pushing" them with a frequency shift, which makes it possible to consider collisions between solitons in a two-channel model emulating the WDM regime of data transmission in a communication line. We conclude that the collisions are strongly inelastic if they take place inside the nonlinear section of the system, and the solitons pass through each other without interaction if they collide inside the linear section.

“…For this reason, 40 Gbps transmission would be limited to few kilometers if compensating techniques of the group velocity dispersion (GVD) were not used [1][2][3]. Dispersion management (DM) is one of the most effective techniques to transmit high capacity on already installed standard SMF links both in the return-to-zero (RZ) [4] and nonreturn-to-zero (NRZ) signal formats [5,6]. DM is through the insertion of a dispersion compensating fiber (DCF) into SMF for eliminating or mitigating the impact of distortion due to GVD.…”

The effects of the variation degree of residual dispersion per span (RDPS) random variables on the compensation characteristics of the distorted signals in optical links with the dispersion management (DM) and the mid-way optical phase conjugator (OPC) are investigated in this paper. In order to obtain this goal, the effective launch power range and the effective net residual dispersion (NRD) range are induced as a function of the variation degree of RDPS random variables. We confirm that it is needed to select the RDPS random variables of the narrow deviation in each fiber spans for implementing the flexible opticallinks transmitting the relative higher launch power. Also, we confirmed that it is more advantageous to use postcompensation rather than precompensation for expanding the effective NRD range.
