The calculator includes:
- Single mode optical fibers: G.652, G.655, and G.657
- Multimode optical fibers: OM2, OM3, OM4
- Brands from leading manufacturers: Corning®, Prysmian/Draka®, and OFS®
- Calculates delay value from distance, or distance from delay value
- A downloadable spreadsheet file for quick access and offline use
