Fiber Chromatic Dispersion Calculator

Estimate accumulated chromatic dispersion and corresponding spectral pulse spread for a uniform fiber segment.

Inputs

Link inputs

Range: -200–200 ps/nm/km

Enter the value for the fiber and operating wavelength from the cable or fiber datasheet.

Range: 0–100,000 km

Use the length of the uniform fiber segment being assessed.

Range: 0–100 nm

Enter the spectral width basis stated for the source; this simple estimate multiplies coefficient magnitude by the entered width.

Result

Accumulated chromatic dispersion (ps/nm)
1,360.00
Estimated spectral pulse spread (ps)
136.00
