KEY FUNCTIONALITY
Component Library
The OptiSystem Component Library includes hundreds of components that enable you to enter parameters that can be measured from real devices. It integrates with test and measurement equipment from different vendors and supports a wide range of optical communication system designs. Users can incorporate new components based on subsystems and user-defined libraries or utilize co-simulation with a third-party tool such as MATLAB or SPICE.

Integration with Optiwave Software Tools
This optical system design software allows you to employ specific Optiwave software tools for integrated and fiber optics at the component and circuit level: OptiSPICE, OptiBPM, OptiGrating, and OptiFiber.

Mixed signal representation
OptiSystem handles mixed signal formats for optical and electrical signals in the Component Library. OptiSystem calculates the signals using the appropriate algorithms related to the required simulation accuracy and efficiency.

Quality and performance algorithms
In order to predict the system performance, OptiSystem calculates parameters such as BER and Q-Factor using numerical analysis or semi-analytical techniques for systems limited by inter-symbol interference and noise.

Advanced visualization tools
This optical system design software includes advanced visualization tools, producing OSA Spectra, signal chirp, eye diagrams, polarization state, constellation diagrams, and much more. Also included in OptiSystem are WDM analysis tools listing signal power, gain, noise figure, and OSNR per channel.

Data monitors
Reliable optical communication system design tools need to be flexible. With OptiSystem, you can select component ports to save the data and attach monitors after the simulation ends. This allows you to process data after the simulation without recalculating. You can attach an arbitrary number of visualizers to the monitor at the same port.

Hierarchical simulation with subsystems
To make optical system design and simulation software flexible and efficient, it is essential to provide models at different abstraction levels, including the system, subsystem, and component levels. OptiSystem features a truly hierarchical definition of components and systems, allowing the simulation to be as detailed as the desired accuracy dictates.

Powerful Script language
Using standard VB Script language, you can enter arithmetical expressions for parameters and create global parameters that can be shared between components and subsystems. The script language can also manipulate and control OptiSystem, including calculations, layout creation, and post-processing.

State-of-the-art calculation data-flow
Our optical system design software’s Calculation Scheduler controls the simulation by determining the order of execution of component modules according to the selected data flow model. The main data flow model that addresses the simulation of the transmission layer is the Component Iteration Data Flow (CIDF). The CIDF domain uses run-time scheduling, supporting conditions, data-dependent iteration, and
