Description
The Cisco NC-57-24DD is a high-density 400 Gigabit Ethernet base line card designed for the Cisco NCS 5500 modular chassis. Built to support large-scale IP and optical transport networks, this line card delivers exceptional throughput, deep buffering, and carrier-class reliability for cloud, service provider, and hyperscale environments.
Featuring 24 QSFP-DD ports operating at 400G, the NC-57-24DD provides up to 9.6 Tbps of aggregate bandwidth per line card. Each port supports flexible speed configurations, allowing operators to deploy 400G today while maintaining backward compatibility with 200G, 100G, and 40G optics. This flexibility enables seamless network evolution without disruptive hardware changes.
Powered by dual forwarding ASICs and optimized for Cisco IOS XR, the NC-57-24DD supports advanced routing, segment routing, telemetry, QoS, and high-scale forwarding. It is ideal for high-capacity core, metro, and data center interconnect (DCI) deployments requiring deterministic performance and future-ready scalability.
