Cisco NCS540 CC SD-AR3K-NC50G24E | 100G QSFP28, Enterprise Router — SD-AR3K-NC50G24E

Handle high-volume network aggregation without forcing compromise at the edge. This Cisco NCS540 configuration is built around dense high-speed connectivity, with 24 110G ports, 8 110/25G SFP/SFP28 ports, and 2 100G QSFP28 ports for environments that need serious throughput and interface flexibility. It is the kind of platform chosen when standard branch routing is not enough. The port mix supports modern transport designs, high-capacity uplinks, and service-provider-style aggregation where interface count and speed directly affect network design options. For teams planning around growth, this chassis class gives room to build without immediately replatforming. Because the configuration is specific and port-rich, it suits infrastructure teams that value predictable scaling and dense optical connectivity. It is a strong fit for core edge, aggregation, and high-speed routing roles where the cost of under-specifying the platform is far higher than the cost of buying the right one once. Ideal For Aggregate high-speed traffic in a service provider or enterprise core edge Terminate dense optical uplinks in a routing fabric Support transport designs that need mixed 110G, 25G, and 100G interfaces Build high-capacity edge routing for growth-sensitive infrastructure Why This Product 1 Offers far higher port density than typical branch routers 2 Combines 110G, 25G, and 100G interfaces in one platform 3 Targets aggregation and transport roles instead of basic office routing 4 Supports optical-heavy designs where interface count drives architecture
