Panel III: Challenges and Solutions for Delivering 400G+ Client and Line Side Optics

Tuesday, 13 March
14:30 - 16:00
Theater I

Andrew Schmitt, Founder, Cignal AI, USA

Panel Description:

Data center switches are scaling from 3.2Tb/s to 6.4, 12.8Tb/s. 25 Tb/s switching chips must be on the horizon. A new generation of 400G front panel pluggable optical transceivers are emerging to support the increased bandwidth. 

Increased electrical speeds of 56 and 64 GBaud and complex signaling and constellations place increased constraints on the packaging and design of optical components. What are the pros and cons of the various pluggable options you’ve evaluated and which direction do you expect to take?
 
  • How should both client and line side optics be accommodated in the same pluggable format?

  • Is there a reason to keep two large and small form factors for client optics to accommodate longer reach applications? Example, CFP2 and QSFP28 at 100G or OSFP and QSFP DD at 400G?

  • Will coherent dominate the 80-100km transmission market long term or are there applications for direct detect?

  • How important is backward compatibility for QSFP28 DD and do you plan to use it?

  • Which applications require pluggables vs. on-board optics? When do we reach the end of the road for front panel pluggables?

  • What are the challenges with COBO and embedded optics? Can the new 400G generation of pluggables, like QSFP-DD and OSFP scale from 400G to 1.6 Tb/s?

  • Is silicon photonics really meeting the speed-density-cost challenges of hyperscale data centers?

  • How is the optical networking value and supply chain changing?
