Ciena Expects Over $10 Billion Backlog by Fiscal 2026 Year-End

Ciena expects to end fiscal 2026 with more than $10 billion in backlog, unrecognized orders, per a September 22, 2026 Lightwave report. That equals roughly six quarters of sales at the third-quarter pace of $1.67 billion. Backlog does not guarantee revenue; orders can be delayed or cancelled, and timing depends on customer deliveries.
