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

Ciena expects more than $10 billion in backlog, meaning unrecognized orders not yet booked as sales, by fiscal 2026 year-end, according to a September 22, 2026 Lightwave report. That is roughly six quarters of sales at the third-quarter pace of $1.67 billion. Backlog is not revenue: orders can be delayed or cancelled, and timing depends on customer deliveries.
