Catalyst 9400 Series 48-Port SFP Fiber Line Card
Product Description
The Cisco C9400-LC-48S is a high-density fiber line card built for modular Catalyst 9400 Series switches, delivering 48 Gigabit Ethernet SFP-based fiber ports for enterprise campus and aggregation deployments. This module enables flexible fiber connectivity across large buildings, campuses, and data distribution layers, making it ideal for environments that require longer-distance, interference-free networking.
Unlike PoE-enabled copper cards, the C9400-LC-48S focuses on high-performance fiber connectivity, supporting multiple SFP transceiver options for multimode or single-mode fiber deployments. It integrates seamlessly into the Catalyst 9400 chassis and is managed via Cisco IOS-XE on the supervisor engine.
