FG-TRAN-SFP+SR Fortinet Compatible 10GBASE-SR SFP+ Transceiver

Fortinet assigns the FG-TRAN-SFP+SR part number to 10GBASE-SR SFP+ modules qualified for FortiGate firewalls and FortiSwitch platforms. The "FG-TRAN" prefix indicates FortiGate-specific qualification, as opposed to the "FN-TRAN" prefix used on Fortinet's generic networking line. Both map to the same 10GBASE-SR optical specification, but each carries distinct EEPROM coding tied to its product family. EdgeOptic's compatible FG-TRAN-SFP+SR replicates the original optical and electrical parameters for direct replacement in FortiGate appliances.

Optical parameters: 850 nm VCSEL transmitter, PIN photodiode receiver, duplex LC/UPC connector, 6.1 dB minimum link budget supporting 300 m over OM3 and 400 m over OM4 multimode fiber per IEEE 802.3ae. The module supports data rates from 1.25 Gbps to 10.3125 Gbps, with the host port determining the active speed. DDM/DOM reports Tx/Rx power, temperature, laser bias current, and supply voltage through the SFF-8472 management interface. Operating range is 0°C to 70°C, SFF-8431/SFF-8432 compliant.

FortiGate appliances use SFP+ ports for HA heartbeat links, LACP aggregation trunks, and dedicated management interfaces depending on the model. The FortiGate 600E, 1100E, and 3700D series are among the platforms with SFP+ cages that accept this module. EdgeOptic codes this compatible with Fortinet-recognized EEPROM data, so FortiOS reports it as a supported transceiver. When ordering for a mixed FortiGate and FortiSwitch deployment, confirm whether the target ports expect FG-TRAN or FN-TRAN coding, as the two SKU families are documented as separate qualification lists by Fortinet; ordering the correct prefix for the target platform is recommended.

CE/RoHS certified and compliant with the SFP+ MSA per SFF-8432. For bulk FortiGate SFP+ orders or platform-specific coding questions, contact our sales team.
