A maker of the fiber-optic gear that carries the world's internet traffic, Ciena builds optical networking, routing, and switching systems used by telecom carriers, cloud providers, and enterprises. Its products include the 6500 Packet-Optical Platform, Waveserver, and Blue Planet automation software. Founded in 1992 by engineer David Huber as HydraLite, the company was renamed Ciena in 1994 when its first CEO, Patrick Nettles, coined the new name. It introduced the MultiWave 1600, the world's first commercially available 16-channel DWDM platform, which helped jumpstart the modern fiber-optic era.
Ciena revenue rose 39.5% to $1.57B as cloud-driven optical demand pushed operating margin to 15.1%, its widest in over four years.
Ciena's more than doubled from a year ago. rose 39.5% to $1.57 billion and widened 3.8 points to 44.0%, as product cost reductions and pricing optimization on optical gear sold to cloud providers more than offset lower manufacturing efficiencies. The quarter leaves the company with its highest in the periods shown, but services margin continues to erode.
Key takeaways
rose 624.3% to $237.9 million and widened 12.2 points to 15.1%, as the increase provided that more than absorbed an 8% rise in operating expenses.
rose 39.5% to $1.57 billion, driven by a 47.1% increase in Networking Platforms to $1.27 billion, fueled by Optical Networking sales—including Waveserver and the 6500 RLS—to cloud and service provider customers.
widened 3.8 points to 44.0%, as product margin gained 5.1 points on cost reductions, pricing optimization, and favorable mix, partially offset by lower manufacturing efficiencies.
Section summaries
Management's Discussion and Analysis
Revenue surged 40% YoY to $1.6B in Q2 FY2026, driven by cloud/AI demand, with gross margin expanding 380 bps to 44.0%.
⌄
Total Q2 rose 39.5% to $1.57B, led by a 47.1% jump in Networking Platforms to $1.27B, fueled by Optical Networking (Waveserver, 6500 RLS) and Routing/Switching (3000/5000 series, 8100 Coherent IP).
improved to 44.0% from 40.2%, as product margin gained 510 on cost reduction, pricing optimization, and mix, partially offset by lower manufacturing efficiencies.
rose to $218.2 million from $9.0 million a year ago, and rose to $1.49 from $0.06, reflecting the improvement against a low base in the prior-year quarter.
was $259.7 million for the quarter, up 65.5% , and rose 70.5% to $218.7 million; the company deployed $344 million for share repurchases in the first half of the fiscal year.
Blue Planet Automation swung to a $2.8 million loss from a profit a year ago, on lower software sales and higher R&D spending.
What changed
The recovery to 44.0%—up from 40.2% a year ago and 43.8% last quarter—partially answers the question raised in Q2 FY2025 of whether margin could recover from that low; product cost reductions and pricing optimization drove the improvement, though services margin fell 4.2 points to 45.4%.
The 39.5% growth rate accelerated from 33.1% in Q1 FY2026, suggesting the cloud-provider optical demand flagged in earlier quarters is not yet decelerating, even as the comparison against the prior year became more difficult.
of 15.1% is the widest since Q2 FY2021, resolving the concern from FY2025 that the 4-5% workforce reduction and exit from 25G PON had not yet produced a measurable decline in operating expenses; the this quarter absorbed the 8% increase in opex.
The historically high noted in Q1 FY2026 was not updated with a specific figure this quarter, leaving open the question of whether orders continue to exceed and whether the backlog contains orders that could be deferred or cancelled once supply constraints ease.
What to watch
Whether the 44.0% can be sustained or built upon, or whether the lower manufacturing efficiencies cited as a partial offset become a larger as volume scales.
Whether services —down 4.2 points to 45.4%—stabilizes or continues to decline as the installed base grows with cloud-provider deployments, and whether the company can reprice maintenance contracts or reduce delivery costs.
Whether the 39.5% growth rate decelerates in the second half as cloud-provider orders are fulfilled and the comparison against the prior-year period becomes more difficult.
The outcome of U.S. tariff investigations into semiconductors and critical minerals, given that the company manufactures substantially all products outside the U.S. and has already cited tariffs as a factor in compression.
Operating expenses grew 8% to $454M, with R&D up 10.7% to $238M to capture AI-driven market opportunities, including advancing WaveLogic coherent modem technology.
nearly doubled to $487M in H1 FY2026; the company deployed $344M for share repurchases (including tax withholding) and $115M in , ending with $1.4B in cash and investments.
profit surged in Networking Platforms (+138.8% to $362M) and Global Services (+23% to $64M), while Blue Planet swung to a $2.8M loss on lower software sales and higher R&D.
