ANNUAL REPORT 2013

Optical Networks & Systems Department (ONS)

Introduction

The goal of the ONS department is to contribute in defining the evolution of future networks towards intelligent (dynamic, self-star), high-capacity, low-cost, scalable, and energy-efficient optical transport networks. To achieve this goal, it focuses on Network Control and Service, to introduce automated and adaptive network functionalities, and Digital Coherent Optical Technology, for high-capacity optical transmission systems. Demonstration is performed by means of the ADRENALINE Testbed®, a test platform designed and developed by the ONS department for experimental research on future optical transport networks.
