Cost Comparison Between IP-Over-DWDM and Other Core Transport Architectures
Overview Cisco recommends an alternative architecture called IP over DWDM, which eliminates the need for Optical to Electrical to Optical (OEO) conversion equipment between the router and the optical layer (including both transponders and SONET gear) by combining DWDM router interfaces with an optically switched DWDM layer. This streamlined core architecture improves the flexibility, power efficiency, and reliability of the core network, while providing significant operating and capital cost savings.
