PROPERTIES OF TEMPORARY OPTICAL SOLITONS IN OPTICAL FIBERS AND THE POSSIBILITY OF THEIR USE IN TELECOMMUNICATIONS. PART 2

Abstract

In the second part of the work, a theoretical study of the propagation processes of pulses having the form of a hyperbolic secant is performed using single-mode optical fibers with allowance for losses. It is shown that the quasisoliton regime in optical fibers disintegrates with increasing distance, but it can be supported by attenuation control, i.e. periodic optical amplification, which can be realized using discrete or distributed amplifiers. The questions of the choice of the lengths of the amplifying regions, the levels of the input signal, the amplification factors of the discrete amplifiers, the levels of the pump radiation of the distributed amplifiers are considered. Simulation modeling of processes in linear paths of fiber-optic communication systems using the OptiSystem and AltPhotonic Simulation Tool is performed.
