Fiber optic transmission systems are used for high-speed traffic transmission in modern telecommunication NGN and IMS networks. Optical channels
of optical transport hierarchy (OTH) communication systems have a bandwidth
of 2.5 to 100 Gbps, so the study of their characteristics is an urgent task. The AQ1
problem of studying the quality parameters (Q-factor) of optical OTH signals of
the OTU1 and OTU2 types is solved in the current section. A simulation model of
an intensity modulated optical transmission system has been developed to solve
this problem. This model contains a transmitter, an optical transmission path with
optical amplifiers and an optical signal receiver. Optical fiber simulation model AQ2
allows to introduce linear and nonlinear distortions of the propagation medium
into the signal and it is based on the Split-Step Fourier Method. The noise of the
optical amplifier was generated by using the inverse discrete Fourier transform
to increase the performance of the model. Comparison of the results of modeling
and analytical calculations was carried out to check the accuracy of the proposed
simulation model. The influence of the signal power of the transmitter and the
quantity of linear path optical sections on the Q-factor of the signal in the receiver
is calculated. It is proposed to optimize the transmitter signal power by the criterion of maximizing the Q-factor to increase the length of the 3R regeneration
section.
