WatchGuard Firebox M 4-Port 10Gb SFP+ Fiber Module | SFP+ Expansion

Extend Firebox capacity with four SFP+ fiber ports designed for high-speed network aggregation. The WG8594 module fits supported Firebox M appliances and adds 10 Gigabit Ethernet connectivity where fiber uplinks are required for distribution, core handoffs, or dedicated service paths. For teams standardizing on optical transport, this module keeps the firewall chassis compact while adding the port density needed for modern rack designs. It is a practical fit for environments that need clean uplink separation, higher bandwidth between network tiers, and fewer external adapters at the edge. Compatibility includes Firebox M470, M570, M670, M4600, and M5600 appliances. With four expansion slots and SFP+ connectivity, the module is suited to deployments where every port must earn its place and where fiber is preferred for distance, signal integrity, or switch-to-firewall aggregation. Choose this module when the firewall is part of the traffic architecture, not just the security stack. It helps preserve performance headroom while keeping the deployment aligned with enterprise cabling standards.
