18.3 Optical Performance
DWDM client cards are grouped into nine classes, shown in Table 18-2. Span loss estimates are based
on the number of spans in the network and the client card class. Some cards belong to more than one
class depending on whether forward error correction (FEC) is enabled and on the payload data type
provisioned for the card.
