comnum.cd_dispersion_factor

comnum.cd_dispersion_factor(fiber, length_km, fs)

The dispersion factor K = -β₂ L fs²/2 of the digital compensation e^{jKω²} (ω in radians per sample; Savory 2008, Eghbali et al. 2014).

Parameters:

• fiber (FiberParams) – the fibre.

• length_km (float) – the length to compensate (km).

• fs (float) – sampling rate (Hz).

Returns:

Return type:

float
