About the FN-TRAN-SFP+LR

The Fortinet FN-TRAN-SFP+LR optical transceiver delivers long-reach 10 Gigabit Ethernet transport for campus backbones and metropolitan disaster recovery links. Utilizing a 1310 nanometer DFB laser transmitter over single mode optical fibre, it bridges geographically separated enterprise buildings up to 10 kilometers without amplification.

Compatibility

Compatible with Fortinet FortiGate enterprise firewalls including 200F, 400F, 600F, 1000D, 1100E, 1800F, 2600F, and 3000 Series models. It integrates natively into FortiOS, supporting real-time Digital Optical Monitoring of transmit power, receive sensitivity, and laser bias current.

How to identify a genuine unit

Housed in an SFP+ metallic enclosure with a blue extraction latch bail that designates longwave single mode optical transmission. The product label clearly displays Fortinet branding, part designation FN-TRAN-SFP+LR, serial tracking barcode, and international regulatory certifications.

Buying used

Inspect optical ferrule surfaces for oil contamination or dust particles using a fiber inspection tool. Connect the optic into a live FortiGate switch port to verify clean link synchronization at 10Gbps full duplex and ensure optical power levels remain within factory parameters.

Works together

How the Fortinet FN-TRAN-SFP+LR 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.
