Panel VII: IP+WDM Architecture Evolution

Thursday, 12 March
14:30 - 16:00
Expo Theater I

Moderator: Helen Xenos, Sr. Director, Portfolio Marketing, Ciena

Panel Description:

The miniaturization of electro-optics alongside advancements in CMOS that enable lower power / footprint are enabling the deployment of coherent optics in smaller pluggable form factors across new areas of the network. These advancements bring with them new opportunities for deploying switches/routers with integrated or coherent pluggable optics, also known as IP over DWDM (IPoDWDM).  Do coherent pluggables eliminate the need for optical transport equipment in the network? Which applications are better served by switches/routers and which are better served by optical transport platforms? How important is line interworking versus higher performance bookended coherent pluggables? What have we learned as part of the standardization efforts led by ITU, OIF, IEEE, OpenROADM, and CableLabs? Beyond the optics, what additional operational aspects are required in the router for viable deployment across a wider range of applications?  What supplementary integration work is required to enable full interworking across optical, management and system layers?  

This session discusses different points of view on the evolution of networks towards IPoDWDM architecture.

Speakers:

Robert Keys, Senior Director R&D Optical Transmission, Ciena, Canada
