Panel II: The Path to Co-Packaged Optics for Switching Applications

Tuesday, 08 March 12:30 – 14:00
Theater I

Session Description:

The industry continues to debate the merits of co-packaged optics and is now reaching the point where deployments of Ethernet switches with co-packaged optics are viable. But viability doesn’t always translate into commercial reality. This panel will review the benefits and challenges around the deployment of co-packaged Ethernet switches from both a technical and commercial perspective. How is CPO affecting investments by the optical and Ethernet component supplier landscape and when will we see deployments in commercially meaningful volumes?
