How to Evaluate Pulse Spreading Time?

Pulse Spreading Time evaluator uses Pulse Spreading Time = Polarisation Mode Dispersion Coefficient*sqrt(Length Of Cable) to evaluate the Pulse Spreading Time, Pulse Spreading Time represents the time it takes for the pulse to spread or broaden due to Polarisation Mode Dispersion (PMD) effects over a given length of optical fiber. Pulse Spreading Time is denoted by t_pmd symbol.

How to evaluate Pulse Spreading Time using this online evaluator? To use this online evaluator for Pulse Spreading Time, enter Polarisation Mode Dispersion Coefficient (D_pmd) & Length Of Cable (L₁) and hit the calculate button.

FAQs on Pulse Spreading Time
