Our Ensemble Simulator precisely mirrors production networks for risk-free testing, training and development. Hosted on a self-provided server or in the cloud, this powerful new software tool enables multiple users to work independently in a virtual sandbox to evaluate configurations, verify APIs and simulate what-if scenarios. With Ensemble Simulator, optical network operators can significantly reduce the cost and unpredictability of network upgrades, accelerate innovation adoption and improve quality of experience for end users.
