Effects of random temperature and pressure influence on the single-channel optical transmission system

In this article we focus on the numerical investigation of random temperature changes in different sections of the optical fibers and their influence on material properties of the fibers. The important issue is to determine whether these temperature changes affect the dispersion and nonlinear effects in the fiber and consequently the transmitted pulse. Moreover, the effects of pressure are also investigated. We found out that the pressure and temperature changes influence dispersion effects in single-channel optical transmission system.
