Network operators first began adopting optical transport network (OTN) switching in the late 2000s as a higher-capacity alternative to synchronous optical networking (SONET) / synchronous digital hierarchy (SDH). Deployments accelerated alongside the adoption of 100G coherent optics in the early 2010s, however, there have been many capacity, technology, traffic, and service evolutions since then.

While some OTN transport functions, such as framing, encryption, and performance monitoring remain relevant for today’s networks, service providers are exploring ways to migrate from legacy designs including traditional core OTN switching to modern, distributed and open architectures. This webcast will explore the latest research findings, as well as the tradeoffs and benefits of these architectures.

Who should attend this free webinar?

Optical communications professionals responsible for the design, deployment, and maintenance of optical transport networks within network operator and communication service provider (CSP) businesses. If you’re a CEO, CTO, Head of Engineering, System Architect or anyone involved in optical transport networks who wants to find out more about new advances in architectures should register to attend this webinar.

Attendees will benefit from a review of the latest service provider research findings and network operator strategies regarding current and future network architectures, from our panel of experts. They will also learn about alternative and evolving network architectures and their tradeoffs including distributed OTN switching and IPoDWDM.
