Historical industry thinking around IP/Optical convergence has narrowly focused on collapsing the IP and optical layers of the network—by simply putting a coherent plug in a router. But convergence requires more than that. To succeed, network operators must take a holistic approach focused on delivering the greatest performance and return on investment. Ciena’s coherent routing brings together purpose-built routers, leading coherent optics, and intelligent flexible photonics—all driven by cutting-edge multi-layer operations. We deliver the simplified multi-layer operations, dynamic scalability, and improved network sustainability operators need to realize IP/Optical convergence success.
