About the FN-TRAN-SFP+SR

The Fortinet FN-TRAN-SFP+SR optical transceiver provides 10 Gigabit Ethernet connectivity for enterprise perimeter firewalls and data center security clusters. Operating at an 850 nanometer optical wavelength over multimode fibre, it enables low latency high throughput connections between FortiGate appliances and core network switches.

Compatibility

Compatible with Fortinet FortiGate 100F, 200F, 400F, 600F, 1100E, 1800F, 2600F, and FortiSwitch platforms equipped with 10GbE SFP+ interfaces. It is recognized natively by FortiOS without requiring custom configuration commands or special licensing keys.

How to identify a genuine unit

Enclosed in a standard SFP+ metallic casing featuring a black optical extraction latch bail that designates 850nm multimode optical operation. The top label bears the Fortinet logo, model identifier FN-TRAN-SFP+SR, serial number barcode, and optical laser safety class markings.

Buying used

Inspect the dual LC optical receptacle with a fiber microscope to verify clean optical surfaces free of scratches or debris. Mount into an active FortiGate SFP+ cage to confirm that FortiOS authenticates the transceiver and displays valid optical power readings in system interface status.

Works together

How the Fortinet FN-TRAN-SFP+SR connects to servers, storage and the network: 3 ways, with the hardware on each path.

iSCSI and NVMe/TCP over EthernetFile storage (NFS and SMB)Hyperconverged cluster

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Storage

iSCSI and NVMe/TCP over Ethernet: how it fits together

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

Hyperconverged cluster

Plan at least two 25GbE ports per node to two switches; all-NVMe clusters often move to 100GbE.
