NeoPhotonics Podcast NeoPhotonics

What comes after 400G? In this episode we discuss various paths to higher speed transmission. We start with a status of the 400ZR/ZR+ modules, then discuss DCI upgrades, OSFP-XD, client side vs line side adoption, and PAM4 vs coherent detection.

Discussion of increasing output power to 0 dBm helping achieve longer reaches and higher data rates, which can only be realized by solving trade-offs including OSNR, optical filtering, cost, size, and  power consumption.

Discussion of what the 400ZR+ means and how it can help carriers and hyperscale operators. Topics include applications, scalability and challenges.

Discussion of 400ZR and 400ZR+ including, how they are defined, used, their impact, deployment in the field, and challenges.  There is a bonus tutorial in the last half of the podcast, which caters to listeners who are new to optical networking. NeoPhotonics guests are Winston Way, Ph.D, and Chief Technology Officer, Ferris Lipscomp, Ph.D, and VP of Marketing, Marc Stiller, M.S. and VP of of Coherent Modules.  Hosted by John Houghton.

Discussion of next-generation ICRs, CDMs, and lasers that are propelling transmission rates of 800Gpbs and beyond using 90 – 96Gbaud components.  Guests include Janet Chen, Ph.D. and Product Line Manager for Coherent Modulator and Receiver, Mike Desmond, Product Line manager, Tunable Lasers, Winston Way, Ph.D. and Chief Technology Officer of NeoPhotonics, and Ferris Lipscomb, Ph.D. and Vice President of Marketing.  Hosted by John Houghton.

Ron Johnson, Senior Director of Product Management and Architecture of Cisco and Winston Way, Ph.D and Chief Technology Officer of NeoPhotonics, discuss IP over DWDM.  This technology has been around for a while, but has not necessarily gone mainstream.  How will 400ZR and ZR+ change this?  Discussion of how are things changing for Cloud and Telecom networks.  Hosted by John Houghton.
