OptiSystem is an optical communication system simulation package for designing, testing, and optimizing virtually any type of optical link in the physical layer of a broad spectrum of optical networks, from analog video broadcasting systems to intercontinental backbones. A system-level simulator. The OptiSystem from Optiwave Systems is an Optical Design Software that facilitates the design, analysis, and simulation of optical systems. It incorporates 600 different components that can be combined to simulate a wide range of optical system configurations and outcomes. This optical design. The new Empirical Laser Measured component will allow designers to more closely match their OptiSystem simulations with manufacturer and lab measurement data of semiconductor lasers.
