Nokia’s optical business declined against an elevated 3Q20, while packet sales continued their steady growth.

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.

Compact modular sales again outperformed the overall optical hardware market while Packet-OTN sales declined. 400ZR is shipping but is supply limited.

Development moves past 90+ GBaud directly to 120+

Ciena starts out the second half of 2021 strong, but supply chain headwinds threaten further growth.

Optical spending by North American Traditional Telco carriers declined YoY; Cloud & Colo optical spending worldwide slowed as NA spending stalled.

First-quarter 2021 worldwide optical hardware spending was down slightly YoY, Chinese optical hardware spending was down significantly.

It was a big quarter for 600G coherent port shipments and sales to Cloud Operators.

Consistent worldwide results and a new effort to close the coherent gap with DCOs.

More ICE6 trials and wins as Infinera now ships for revenue; 600bps port shipments rebound.

Record Q2 profitability – Sales hit by 10% due to supply chain issues – EMEA continues to rebound

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.

400Gbps+ port shipments doubled YoY, 400ZR ports started to ship, and compact modular sales significantly outperformed the overall optical hardware market this quarter.

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.

Ciena is well-positioned to return to growth in the second half of 2021 as multiple factors align in its favor. 

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.

Optical spending by North American Traditional Telco carriers declined steeply YoY compared to a heavily frontloaded 1Q20, but show signs of longer term recovery. Cloud & Colo optical spending worldwide slowed as NA spending stalled in 2020 and APAC is just beginning to take off.
