Group Delay Dispersion Calculator calculator can be used to calculate the group delay dispersion of optical fibers based on material properties and wavelength.
Learn how to use the Group Delay Dispersion Calculator calculator and its working principles
Group delay dispersion (GDD) is a measure of the dispersion of a medium for pulses of light with a pulse width much smaller than the coherence length of the medium. It is defined as the derivative of the group delay with respect to frequency.
The group delay dispersion is calculated using the formula:
D = (λ² / 2πc) * (dn/dλ)
Where:
Group delay dispersion is an important parameter in optical communications and fiber optics, as it affects the bandwidth and pulse broadening in optical systems. It is critical for designing optical modulators, filters, and other communication components.
