Modulation Compatibility
Multi-subnet
network where the various subnets work with different sets of signal classes, i.e., the metro subnets work with 10G
NRZ and 40G NRZ while the
long haul subnet works with 10G NRZ and 40G NRZ. The regenerators on the DWDM links connecting the subnets can be used to
perform modulation format
conversion between 40G NRZ and 40G RZ signals.
