In the example above, the DWDM boxes connected between the two Primary Data Centers are configured
with multiple dark fibre links. The DWDM links are used for both networking and CA data replication. If
the DWDM box is fault tolerant, only one is required in each data center. If it's not fault tolerant, two are
required in each data center. The Quorum Server site distance can be up to 100 kilometers away from
either Primary Data Center since DWDM links are also used. It is also supported to connect to the
Arbtitrator data center without DWDM links, as long as the distance is within the allowed specifications for
the network type being used.
