Ciena and Nokia are both benefiting from surging AI and cloud demand for optical networking solutions. Ciena expects 30% revenue growth in fiscal 2027 with an $8.5 billion backlog, while Nokia targets 25-30% growth in its Optical and IP Networks segment.
However, both face supply constraints and rising costs. Ciena holds a Zacks Rank #1 (Strong Buy) with positive earnings revisions, while Nokia has a Rank #3 (Hold) with no estimate changes, making Ciena the more attractive investment despite its premium valuation.
