چکیده
This paper presents an overview of the fiber optics and its principles in optical communication network. Fiber nonlinearities are bounded factors for optical communications systems, in specific for wavelength division multiplexing .Among the nonlinearities effect is four-wave mixing ,which is a nonlinear process that generates new frequency components from existing frequency components. FWM is the primary factor which ultimately restricts the channel density and capacity of WDM systems. In the ROF-WDM system, the optical modulation technique plays an imperative role in amount of fiber nonlinearity impact. Various aspects of fiber optics and its related parameters in terms of different elements have been touched in this paper. Keyword: Wavelength division multiplexing (WDM); Radio over fiber (ROF); Four Wave mixing (FWM).

متن کاملDispersion Evaluation In Optical Wave Guides
One of the factors which limits the transmission capacity of the fiber optics communication channel is the material dispersion. Exact analytical study of the material dispersion is often complex and involves calculating the derivatives of the refractive index of the core. These calculations are too cumbersome to do, especially for high-order derivatives. So material dispersion has only been stu...
