One of the most dominant degradation effect in the optical communication systems with wavelength division multiplexing is four-wave mixing. The development of optical networks in recent years has caused increasing demands on the transmission capacity. The transmission capacity can be increased by using advanced modulation formats. In this paper, the effect of four-wave mixing in multi-channel optical...
Nowadays increase of data transmission leads to the improving optical communication and data systems. One of the challenges are how effectively utilize bandwidth of the transmission media. Wavelength division multiplexing is common used method of multiplexing to create high-speed full-optical networks. Increase of transmission capacity can be achieved by using high-order modulation formats. This paper...
This article deals with the numerical model of degradation mechanisms in a single-mode optical fibre. Signal propagation in a single mode optical fibre is described by nonlinear Schrödinger equation and is numerically calculated with the use of Finite Difference Method. Created numerical models provide good description of the degradation mechanisms investigated transmitted optical pulses. Implemented...
