Optical Networking / DWDM Basics (Dense Wave Division Multiplexing)

Optical networking delivers the distance, bandwidth scalability, resiliency, and manageability that broadband networks require. Slides are available here https://ribboncommunications.com/company/get-help/glossary/what-is-dwdm You're invited to a special session from Ribbon on Tuesday, December 15th where we will review optical networking technology and basics and explain how optical networks solve reachability, survivability, bandwidth growth, and maintenance challenges for broadband services. Key topics of discussion: What problems do optical networks solve? What are the major piece parts and important vocabulary? What do I have to think about when deploying? Any cool stuff on the market I should be aware of? 0:00 Introduction 1:15 Ribbon for IP and Optical 3:31 What Can an Optical Network Do for Me? 5:09 A couple DWDM basics... 7:27 What are the Key Pieces of an Optical System?
