Cisco Optics Podcast Episode 7
Overcoming the next hurdle to get to 800G pluggable optics, a conversation with Mark Nowell, part 3 of 4.
What are the industry’s technical experts in pluggable optics thinking about today? What are the technical boundaries that the smartest minds are pushing past to make the next generation of high speed optics? In episode 7, we continue a conversation with my esteemed colleague, Mark Nowell. In this third part of our four-part conversation we continue on the topic of thermal considerations, which he’s been thinking and writing about lately.
