Description
The Cisco Catalyst C9400-LC-48S is a high-density 48-port Gigabit Ethernet SFP fiber line card designed for the Cisco Catalyst 9400 Series modular switches. Built for enterprise core, distribution, and aggregation layers, this line card delivers non-blocking, line-rate 1G fiber connectivity to support scalable and resilient campus and service-provider networks.
Supporting advanced enterprise features such as MACsec encryption, jumbo frames, and full integration with Cisco Catalyst 9400 supervisor engines, the C9400-LC-48S is ideal for Fiber-to-the-Desktop (FTTD) deployments, DSLAM and PON aggregation, and mobile backhaul environments where consistent performance and high availability are mandatory.
With flexible SFP optic support and enterprise-grade reliability, this line card enables secure, future-ready fiber access while maintaining full compatibility across Catalyst 9400 chassis configurations.
