WatchGuard Firebox M 8 Port 1Gb SFP Fiber Module
Supports optical fiber cable for durable performance, minimal signal loss, and fast data transfers to greater distances. Up to 10x faster than standard Ethernet connection and provides high-performance. With 1000Base-X technology, get up to 1000Mbps data transfer rate over supported network cable.
The eight SFP interfaces are numbered from 0 to 7. To use these interfaces you must plug in a compatible SFP transceiver.
Each SFP interface has two indicators. Indicators are located in the center of the interface module, between the upper and lower row of interfaces. Indicators that point up (▲) show the status of the upper interface. Indicators that point down (▼) show the status of the lower interface.
For each interface, the left indicator shows activity, and the right indicator shows the link status.
