Abstract

Open optical networks present a variety of benefits to service providers and enterprise network operators, such as freedom from single-vendor dependence and the potential to select best-in-class solutions for each individual network role (e.g., line system or optical terminals). In this paper, we discuss two open optical network models: one enables transponder–line system interoperability, whereas the other goes a step further and enables line system–line system interoperability. We examine these models in more detail in the context of an open optical system already deployed at scale. We present real-world experiences and lessons learned with respect to optical link design, software and controls, deployment, and operation, as well as recommendations for future evolution of the network.
