1.
Each DCM is designed to compensate for a specific amount of dispersion. For example, the DCM 20 is designed to
compensate for 20 km of dispersion, and the DCM 30 is designed to compensate for 30 km of dispersion.
compensate for 20 km of dispersion, and the DCM 30 is designed to compensate for 30 km of dispersion.
2.
Inclusive fiber loss, splice loss and one connector-connector interface loss.
3.
RDS = Relative Dispersion Slope, dispersion slope divided by dispersion.
4.
Average Polarization Mode Dispersion (PMD) measured using the interferometric method.
