DWDM is often used by telecommunications, cable and data centers as part of their optical transport network.

Carrier Transport Network

The carrier transport network is made up of several layers of aggregation called the access network, metro aggregation network, edge network and the core backbone network. DWDM is most often used in the metro aggregation network and the core backbone network.

DWDM in the metro aggregation network is used to combine data from several cities. As service providers bring more computing capabilities closer to their customers, DWDM is also flexible enough to meet their needs for higher bandwidth aggregation as they begin to converge more data into a single node to compute. The core backbone often deals with the high-speed switching of large amounts of data between their major central offices, which can span across several regions, states or even countries, which is also ideal for using DWDM.
