Cisco FPR4K-NM-8X10G 8-Port 10GbE SFP+ Network Module

Expand compatible Cisco Firepower 4100 Series appliances with the FPR4K-NM-8X10G, an eight-port 10GbE SFP+ network module designed to add flexible high-speed optical connectivity. It is a practical fit for security infrastructure that needs additional interfaces for network segmentation, uplinks, service-chain design, or high-bandwidth connections between Firepower appliances and the surrounding data-center network. The modular format supports a cleaner appliance expansion strategy than replacing the entire security platform.
