Here is a sneak peek of the hot topics of discussion at OFC 2022

How will the adoption of 400ZR and ZR+ pluggable coherent modules impact Metro WDM equipment spending?

The historical classification of coherent optical technology (Gen1, Gen2, etc.) is no longer sufficient. Therefore, Cignal AI will now recognize and classify coherent DSP technology by its maximum baud rate and whether the DSP is optimized for Performance or Compact applications.

Development moves past 90+ GBaud directly to 120+

Nearly 5 years after the project’s inception, AT&T disclosed it has deployed OpenROADM-based networks across a dozen US metros.

After years of anticipation, 400G pluggable digital coherent optics (DCO) will finally achieve general availability and initial deployment in 2021.

Quick thoughts on equipment spending trends as well as a current view on the role of pluggable coherent modules.

Several vendors are shipping 800Gbps capable coherent optical solutions, and now the industry must consider the next steps in development.

Co-packaged optics (CPO) moved from hero experiments to discussions of commercial roadmaps this year. In this update from OFC21, we cover the key points about CPO discussed at the show.

Cignal AI continues to track announcements of 5th generation (800Gbps-capable, 90+ GBaud) optical trials and deployments.

Infinera provided new details on ICE6, XR Optics, Groove Compact Modular, and opportunities to displace Huawei.
