Preliminary Summary and Highlights


  • The worldwide optical market declined by -4% due to continuing supply chain constraints and weakness in China, Europe, CALA and Japan. Excluding China, the optical market grew 2%.
  • The worldwide routing market grew 2% for its fifth straight quarter of growth and reached record quarterly and full-year revenues.
  • Supply chains are improving but remain strained, impacting product delivery and customers’ ability to accept and deploy new hardware.
  • Currency effects continue to distort dollar-denominated results.


  • Driven by India, RoAPAC optical spending increased 26% and routing grew 9%.
  • North American optical and routing sales each grew 14% to reach record 4Q and full-year levels.
  • EMEA’s optical and routing sales declined -7% and -4%, respectively, due to high energy prices and elevated expenses stemming from the war in Ukraine.
  • Optical sales in China declined -15% as the chaotic transition from zero-COVID policies disrupted markets.

Customer Markets

  • Optical sales to Cloud & Colo operators fell -3% compared to a drop of -4% in the overall market. Recent layoffs at the major North American hyperscalers do not appear to reflect a decline in network capex. The segment likely would have grown if it were not for Ciena’s ongoing supply chain issues.
  • In routing, Cloud and Colo again grew the fastest among customer segments with 7% growth. Routing sales to Cloud & Colo operators grew 13% in 2022 compared to 3% in Service Provider and 2% in Enterprise.
