NeoPhotonics Podcast

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 […]

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. […]

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 […]

First generation data center interconnects can now boost fiber capacity by 800% with upgrades and by moving from 100GHz to 75GHz channel spacing.  John Houghton interviews Winston Way, Ph.D and Chief Technology Officer of NeoPhotonics on how to realize this capacity increase.   

NeoPhotonics VP Marc Stiller and John Houghton discuss pluggable modules including definitions, how they can be used in data center interconnects, important characteristics, and what makes NeoPhotonics modules unique.

As radio bandwidth becomes saturated, the interest in optical communications in space is increasing because data transmission in space is much faster and more secure.  Join NeoPhotonics VP, Nicolas Herriau, and John Houghton as they discuss the future of space connectivity.

Laser linewidth is the finite spectral width related to phase fluctuations in emitted laser light. A lower linewidth implies a purer laser frequency. If a laser’s phase noise is zero, it has a single pure frequency, which is just a line in the frequency domain. Ergun Canoglu, PhD and Director of Sensor Products is interviewed […]

Why narrow laser linewidth, which implies low phase noise, is a critical parameter for lasers used in coherent systems.  Winston Way, PhD and Chief Technical Officer at NeoPhotonics is interviewed by John Houghton.

How to get more bandwidth through existing fiber by using optical coherent detection and optical spectrum expansion technologies.  Winston Way, PhD and Chief Technical Officer at NeoPhotonics is interviewed by John Houghton.

Description: Discussion of network traffic between data centers, why bandwidth capacity is running short, and how NeoPhotonics 400ZR modules can help.  John Houghton interviews Marc Stiller, VP of Lineside Product Management.

What is the Super C-Band and how can it open up more bandwidth on fiber optic networks?  Ferris Lipscomb, VP of Marketing at NeoPhotonics discusses Super C-Band and the C++ with John Houghton and how it increases the limits of fiber capacity in applications from interconnecting data centers to long haul telecommunications.
