OPT-1041: Introduction to Next-Generation Intelligent DWDM Networks
The falling prices of optical components coupled with the adoption of 10-Gbps technology has enabled the next generation of dense wavelength-division multiplexing (DWDM) networks. The intelligence required to provision, monitor, and maintain these networks is moving from the network administrator to the network elements. Layer 1 phenomena such as nonlinear effects, chromatic dispersion, optical noise, and fiber degradation along with network-affecting disruptions caused by operator error can now be detected, isolated, and, in some cases compensated for, by the network itself. This presentation details the most common Layer 1 limitations that a customer will face, along with how the network can avoid or mitigate them. A section delineating the advantages of this new intelligent network, such as less down time because of faster fault isolation and auto fault recovery, as well as lower maintenance costs because of the ease of provisioning new services, is also included.
