| description | This thesis presents analytical and numerical investigations of optical soliton
transmission in optical fibre communication systems. The basic principles of
nonlinear pulse propagation in optical fibre are discussed followed by discussion of
the main limitations for an amplified soliton based system. The goal of this work is to
study in-depth the soliton propagation and to analyse the bit pattern noise analysis and
multi-slot analysis of system performance. First, a performance comparison of
mqocss, VPI and OptSim for single and WDM transmission systems is presented. The
purpose of this comparison is to assess the degree of variability between
independently written numerical simulation codes and the commercial software
available in the market. Secondly, a study of average soliton systems with 35, 50 and
70 km amplifier spacing is presented both analytically and numerically. 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. The introduction
of optimum jitter parameter, αsq = 0.05 in the formulation of GH limitation and
optimum ratio of Belec to Bopt, BRAT = 0.4, of the ASE limitation improve the better
comparison between analytical and numerical results. 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. Finally a significant portion of this work is devoted to the noise analysis of
GH and SNR limited system transmission. A novel technique is introduced which is
designed to distinguish between the effects of dispersion and jitter in analysing the
limitations of system performance. These are represented in the form of probability
distribution function on amplitude and timing jitter, by introducing the two methods
(A and B), referring to the eye diagrams of the system limitations. Another technique
analysis is presenting the energy plots of En+1 and En-1, the energy adjacent to bit
under consideration. The plot also explains the limitation due to amplified soliton,
ASL.
