Following are the major parameters associated with fibers:
-
- Forward attenuation/km
- Backward attenuation/km (if asymmetric)
- Polarization mode dispersion
- Polarization-dependent loss (PDL)
- Dispersion (chromatic and material)
- Zero-dispersion wavelength
- Dispersion flatness over spectrum range
- Birefringence
- Cutoff wavelength.
