Eight-port Gigabit SFP fiber module

The WatchGuard WG8593 expansion module adds eight SFP mini-GBIC slots to compatible Firebox M-series appliances. It is designed for administrators who need to extend firewall connectivity over optical fiber links. The module supports Gigabit Ethernet at 1000Base-X speeds for data and optical networking applications.

Sustained line-rate throughput on all ports

Each of the eight SFP cages operates at Gigabit line rate without shared bandwidth bottlenecks. The module maintains consistent packet-forwarding performance during continuous traffic loads across multiple fiber links. Thermal design matches the host appliance airflow so sustained operation does not throttle port speed.

Verify Firebox model compatibility first

The module is qualified only for Firebox M470, M570, M670, M4600 and M5600 platforms. Older or smaller Firebox models lack the required expansion bay and firmware support. Confirm the exact appliance model and available slot before ordering.

Questions about this item

Does the 8-port SFP fiber module generate noticeable heat or noise when installed in a Firebox M470 running continuously?

The module is a passive SFP expansion card with no onboard fans or active cooling; heat and noise depend on the host firewall's own thermal design.

Which SFP transceivers must I already own to populate the eight mini-GBIC slots on this WG8593 module?

You need eight 1000Base-X compatible SFP (mini-GBIC) transceivers matching your fiber type and distance requirements; the module itself ships empty.

Can I add this 8-port fiber module to an older Firebox M4600 without upgrading the appliance firmware?

The WG8593 is listed as compatible with the M4600; firmware requirements are determined by the firewall OS, so consult the vendor's release notes for the minimum version.
