Method and sources
Revenue by geography as tagged in the XBRL of Ciena’s latest three annual reports (10-K or 20-F). Region and country names are the filing’s own wording. Share = region ÷ the filing’s total revenue for the same fiscal year. Regions are the filer’s own definition (customer location or ship-to, see the filing); nothing is converted, estimated or split.
For each fiscal year the newest filing wins. A dashed line in the chart marks a structural break: the filing reports a different set of regions than the year before, so shares are not directly comparable across it.
