Telecom carriers and cloud providers buy its transport systems, pluggable optics, and network software. Its AI-relevant portfolio includes WaveLogic coherent optics, the Manage, Control and Plan automation suite, Blue Planet AI network software, and Adaptive IP. WaveLogic technology in particular carries the growing rivers of traffic that AI workloads generate between facilities. Founded in 1992 and headquartered in Hanover, Maryland, Ciena trades on the NYSE, is led by CEO Gary Smith, and employs roughly 8,900 people. ## Role in the AI buildout Ciena sits in the Networking & Optics layer, carrying AI traffic between and inside data centers. Training and serving AI models generates enormous data flows that have to move over coherent optical links, and cloud provider spending on that AI-driven interconnect bandwidth is now Ciena's key growth engine. Its large telecom carrier base sits alongside that story, giving it a mature revenue foundation. Supercycle scores its exposure as substantial, driven by cloud and AI bandwidth demand. ## Tracked investors holding it (13F) | Investor | Fund | Position value | Portfolio % | Change | Period | | --- | --- | --- | --- | --- | --- | | [Gavin Baker](https://supercyclehq.com/investors/gavin-baker) | Atreides Management | $337.8M | 3.03% | increased | 2026-06-30 | | [Ray Dalio](https://supercyclehq.com/investors/ray-dalio) | Bridgewater Associates | $49.6M | 0.20% | trimmed | 2026-06-30 | ## Recent news - [Ciena Eyes 30% Revenue Growth in FY27: Can Strong Demand Sustain It?](https://finance.yahoo.com/technology/articles/ciena-eyes-30-revenue-growth-130500024.html?.tsrc=rss) (source, 2026-11-06) - [Ciena Stock Outlook Hinges On Backlog Growth and Earnings Recovery](https://finance.yahoo.com/markets/stocks/articles/ciena-stock-outlook-hinges-backlog-081237475.html?.tsrc=rss) (source, 2026-11-06) - [Cisco Falls 7% on Morgan Stanley Downgrade; Ciena Plunges 15%, Arista Networks Tumbles 10%](https://247wallst.com/investing/2026/11/05/cisco-falls-7-on-morgan-stanley-downgrade-ciena-plunges-15-arista-networks-tumbles-10/?.tsrc=rss) (source, 2026-11-05) - [Ciena, Nokia, and Cisco Named Leaders in ABI Research’s Open Line Systems for Data Center Interconnect Scale-Across Ranking](https://finance.yahoo.com/technology/articles/ciena-nokia-cisco-named-leaders-140000510.html?.tsrc=rss) (source, 2026-11-05) - [Can Ciena Stock Fall 40%?](https://www.trefis.com/stock/cien/articles/622822/can-ciena-stock-fall-40/2026-11-05?.tsrc=rss) (source, 2026-11-05) ## FAQ ### What does Ciena do?
