Based on realistic modeling of fiber optics, semiconductor lasers, amplifiers, and signal processing, OptiSystem allows users to simulate scenarios ranging from simple point-to-point links to complex dense wavelength division multiplexing (DWDM) networks and long-haul transmission systems.
One of the most critical functions of OptiSystem is its ability to account for . In a vacuum, light travels perfectly; however, in a fiber optic cable, signals suffer from attenuation, dispersion (chromatic and polarization mode), and non-linear effects like Four-Wave Mixing (FWM). OptiSystem uses advanced mathematical algorithms to predict how these factors will degrade signal quality over long distances. This allows researchers to troubleshoot and refine a system before a single piece of hardware is ever purchased. Visualizing Performance
At its core, OptiSystem is an innovative, comprehensive, and powerful software tool for designing, testing, and simulating optical fiber communication systems.
Typical steps in OptiSystem:
