The future points toward fully automated photonic design, where OptiSystem acts as a backend engine for Python-based workflows (API-driven simulation) and cloud-based high-performance computing clusters.

Undersea cables are the backbone of the internet. Engineers use OptiSystem to model transoceanic links spanning 6,000 km or more. They simulate:
