Web Calc Online Design
Always use the same units (inches or mm) in each calculation (unless indicated).
Enter your numbers into the light orange-colored cells. To recalculate, press the TAB
key, or click in another blue box, or click the Update button. Other formulas you’d

Type of Fiber: * are most popular/recommended.
Useful Wavelength Ranges: Borosilicate – 400-1600nm, Fluoride – 450-5000nm, Plastic – 400-1100nm, Singlemode – Specified in description, UV Fused Silica – 190-1400nm, WF Fused Silica – 500-2200nm.
Numbers with backslashes indicate the core/clad/buffer diameters (um). Abbreviations are:A = Acrylate Buffer 85C, HUV&HWF = Hard Clad, NA= Numerical Aperture, P = Polyimide Buffer 400C, P22 = Polyimide Buffer .22NA, T = Tefzel Buffer 150C, UVNS = Non Solarizing, WF = Water Free = IR.
Overall Length: Standard borosilicate is 6 meters long, special order 12 meters long.
Number of Legs: enter 1 for a single bundle, 2 for bifurcated (2 legs), etc.
Common Bundle Diameter: alter this cell if you want to control the number of fibers.
Center Wavelength: in nm, or enter ‘VIS’ for average 400-700nm, ‘NIR’ for 700-1600nm, or ‘UV’ for average 200-400nm.
Connectors: SMA is most popular, positive lock, 2.5mm max bundle. CPC is circular plastic connector, good for multiple bundles. Line, rectangle, hex, ring, and mask are custom housings.
Stripping: Removing the fused silica buffer allows the fibers to be more tightly packed, but makes the fibers more fragile. Borosilicate and plastic have no buffer.
External Transmission: accounts for all of the losses (internal, reflection, packing (85%), and core/buffer area ratio).
Internal Transmission: considers only the loss inside the fiber.
Broken Fiber Allowed: shown is 5% for borosilicate, 2% all others.
