Optical Limitations

Attenuation in fiber (dB loss)

Chromatic Dispersion (CD)

Polarization Mode Dispersion (PMD)

Non-linear Optical Fiber effects

Due to non-linear index of refraction:

Four Wave Mixing (FWM)

Self Phase Modulation (SPM)

Cross Phase Modulation (XPM)

Due to stimulated scattering:

Raman

Brillouin

Ultimately: Optical Signal to Noise Ratio (OSNR)
