Summary and Highlights


  • The worldwide optical market grew 4%. Cloud operators continue to invest in transport, and vendors are still shipping against the large backlogs accumulated during the supply chain challenges of the past 18 months.
  • The worldwide routing market fell -4% following the first half of 2023 in which it skyrocketed 16%.
  • Supply chains have largely recovered, but macroeconomic concerns are causing some network operators to pause orders, delay projects, and postpone delivery of ordered hardware by several quarters.
  • 5G-related transport spending has peaked and is now declining in countries that were early to deploy the technology, but it continues to be a growth driver among later adopters.


  • North American 3Q23 optical revenue dropped -5%, its second quarter of decline following 18 months of rapid growth. Routing revenue paused following eight straight quarters of growth, dropping -2%.
