Cisco NCS-57B1-5D24H-SE Chassis | 5x400, 24x100 QSFP-DD — NCS-57B1-5D24H-SE

Concentrate high-speed traffic in a chassis built for fixed-scale service-provider deployments. The Cisco NCS-57B1-5D24H-SE is configured for 5x400 and 24x100 all QSFP-DD connectivity, giving infrastructure teams a dense foundation for aggregation, transport, and edge routing roles that need substantial bandwidth without the complexity of modular growth. This platform is suited to environments where design discipline matters. Fixed-scale architecture helps standardize capacity planning, simplify deployment patterns, and reduce the variability that can come with mixed hardware builds. For operators managing backbone, metro, or large campus interconnects, the chassis provides a clear path to high port density and consistent operational behavior. It is the kind of hardware you choose when the network must carry more traffic with fewer moving parts. Instead of adding complexity, it concentrates capability into a purpose-built chassis that aligns with service-provider expectations for scale, repeatability, and long-term infrastructure planning. Ideal For Service-provider aggregation nodes requiring dense QSFP-DD port concentration Metro transport platforms with fixed-scale bandwidth planning Backbone edge deployments that need standardized high-speed chassis design Large-scale routing environments where predictable hardware footprint matters Why This Product 1 Fixed-scale chassis reduces deployment variability versus modular builds 2 QSFP-DD-only design supports standardized high-speed optics planning 3 5x400 and 24x100 capacity targets dense transport and aggregation roles 4 Purpose-built for service-provider environments rather than general-purpose switching
