Abstract

This paper considers the single channel soliton system where the predictions of the analytical models are compared with the numerical simulations of the system performance. To overcome the effect of loss in long-haul light wave systems, solitons should be amplified periodically to compensate for the losses. However even with the discrete periodic amplification, launching with the ideal, lossless peak power will not give the balance between non-linearity and dispersion required to create a soliton. In order to achieve the balance, average soliton system/guiding center soliton is used where a pulse with an enhanced peak power is launched so that the average power over the propagation between amplifiers is equal to the soliton power in a lossless system. In order to improve the performance in propagation of soliton systems, it is necessary to resist signal to noise ratio (SNR) degradation and Gordon-Haus jitter accumulation. This is done using the guided soliton system where the system has in-line filters which prevent the frequency of the soliton from drifting as a result of the accumulated ASE noise and hence suppress the GH jitter. The effect of modifying the existing rule of thumb formulae is presented in terms of a design diagram. This is then compared to the numerical simulations. A series of design diagram with Gordon-Haus (GH) jitter, signal to noise ratio (SNR) and soliton collapse limited transmission is also introduced. The same study has been repeated for guided soliton systems.
