Learn about the transformative technology of Pluggable Digital Coherent Optics (DCO) in this 56-minute NANOG conference talk. Discover how DCO enables routers to integrate coherent DWDM interfaces without specialized hardware, leveraging power-efficient QSFP56-DD transceivers in standard 400GE ports. Explore the cost benefits of replacing traditional DWDM transponders with DCO and understand the Routed Optical Networking architecture that combines DCO with IP/MPLS innovations for optimized packet switching. Gain insights into managing DCO technology in routers, including optical parameter monitoring, fiber performance management, and data visibility considerations. Examine the role of Digital Signal Processors in optical signal monitoring, transport encapsulations, and their impact on IP network operations. Delve into industry standards and open networking initiatives supporting multi-vendor ecosystem development, presented by speaker Emerson Moura.
