Notes:
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.
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.
This module is designed to operate up to 24 wavelengths. Applications beyond this will require a unique fiber design to
compensate the dispersion over a broad number of wavelengths. Please contact your Applications Engineer for this request.
