This useful reference tool enables you to quickly calculate the latency / optical time delay for any length of the most widely deployed single-mode and multimode optical fibers.  

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
