OptSIM

OptSIM is a system-level simulation platform designed for optical communication networks and photonic integrated systems. It helps analyze and optimize signal behavior across complex optical environments. It provides a virtual design environment to evaluate transmission effects before physical prototyping, reducing development effort and improving validation workflow.

OptSIM Key Capabilities

System-Level Optical Simulation – Models end-to-end optical communication systems including fiber, components, and network behavior.
Advanced Modulation & Transmission Analysis – Supports coherent and high-speed modulation formats such as QPSK, QAM, and OFDM.
Real-World Signal Impairment Modeling – Simulates dispersion, noise, nonlinear effects, and interference in optical systems.
Integrated Optical & Electrical Co-Simulation – Enables combined simulation of photonic and electronic signal behavior.
Virtual Prototyping Environment – Allows rapid testing and optimization of multiple system configurations before deployment.
Comprehensive Measurement Tools – Includes BER, eye diagrams, spectrum analysis, and signal performance metrics.

ModeSYS

ModeSYS extends the simulation flow for optical communication and signal behavior analysis. It is used when system-level modeling needs to include detailed mode-related or communication-oriented analysis within the broader OptSIM workflow.

Why OptSIM is Used?

OptSIM is widely used to validate optical system performance before deployment because it:

Enables accurate system-level simulation of optical networks
Reduces dependency on costly physical prototyping
Helps analyze transmission effects and signal limitations
Supports advanced modulation and high-speed communication design
