Fortinet compatible FG-TRAN-SFP28-SR Description

EdgeOptic's FG-TRAN-SFP28-SR compatible is a Fortinet-coded 25GBASE-SR SFP28 transceiver, a direct replacement for Fortinet's FG-TRAN-SFP28-SR optical module. It ships with Fortinet-recognized EEPROM, so FortiGate NGFW chassis identify the module as a native Fortinet 25G SR optic. FG-TRAN-SFP28-SR and FN-TRAN-SFP28-SR are distinct Fortinet ordering codes for the 25GBASE-SR SFP28 transceiver; procurement should order against the exact prefix the Fortinet quote specifies.

Optical performance follows IEEE 802.3by Clause 112: 100m reach on OM4/OM5 multimode fiber, 70m on OM3. Transmit power is -8.4 to +2.4 dBm, receive sensitivity -10.3 dBm, link budget 5.3 dB with host RS-FEC (IEEE 802.3by Clause 108). The module uses an 850nm VCSEL transmitter, a PIN photodiode receiver, and an LC/UPC duplex connector. DOM is exposed per SFF-8472. Line rate is 8.5 to 25.78 Gbps, covering both 10GBASE-SR and 25GBASE-SR host rates. Power consumption is 0.3W maximum over the 0 to 70°C commercial case temperature range.

FG-TRAN-SFP28-SR is the procurement SKU for the 25G SFP28 slots on the FortiGate F-series NGFW chassis that carry SFP28 cages: FortiGate 100F/200F Series (front-panel SFP28 ports), FortiGate 1000F, and higher-capacity FortiGate 3000F/4000F models. Entry-level FortiGate chassis without SFP28 slots and earlier 10GE SFP+ FortiGate generations are out of scope for this module. The authoritative reference for the specific FortiGate chassis and FortiOS release combinations that accept FG-TRAN-SFP28-SR is the Fortinet transceiver datasheet; confirm the chassis-plus-FortiOS validation before commissioning in a production network.

Two distinct Fortinet ordering codes reference 25GBASE-SR SFP28 transceivers in current catalogs: FG-TRAN-SFP28-SR and FN-TRAN-SFP28-SR. They are separate catalog entries and are not interchangeable on a Fortinet BOM. Buyers sourcing against a current FortiGate price list should verify which prefix the chassis vendor or Fortinet reseller has quoted and order accordingly; this page targets the FG- ordering code specifically, and the FN- ordering code is sourced from the separate FN-TRAN-SFP28-SR catalog entry.

DOM readout on FortiGate follows the SFP28-port optical telemetry surfaces that FortiOS exposes for transceivers: the SFF-8472 parameter set (transmit power, receive power, laser bias, case temperature, supply voltage). The exact CLI or web-UI path varies by FortiOS release; the FortiOS CLI reference for the running chassis image is the authoritative source. Every unit is factory-tested to the 25GBASE-SR optical specification per IEEE 802.3by Clause 112. Certifications: CE, RoHS, Class 1 FDA, IEC 60825-1. Link-side fiber choice follows the standard 25GBASE-SR class: OM4 or OM5 for the full 100m reach, OM3 for 70m; OM2 and OM1 fall outside the 25G supported-fiber list entirely.

Frequently Asked Questions

Which FortiGate models use the FG-TRAN-SFP28-SR?

The 25G-SFP28-capable FortiGate chassis families: FortiGate 100F/200F Series (25G SFP28 front-panel ports), FortiGate 1000F, and FortiGate 3000F/4000F at the higher-capacity end of the NGFW line. Earlier FortiGate 10GE SFP+ generations and entry-level FortiGate chassis without SFP28 cages are out of scope for this module. The Fortinet transceiver datasheet is the authoritative reference for specific FortiGate chassis and FortiOS release combinations; verify against the datasheet revision that matches your FortiOS image before provisioning in production.

Is FG-TRAN-SFP28-SR interchangeable with FN-TRAN-SFP28-SR on a Fortinet BOM?

Not interchangeable in procurement. FG-TRAN-SFP28-SR and FN-TRAN-SFP28-SR are distinct Fortinet ordering codes that map to separate catalog entries; substituting one for the other on a Fortinet BOM will fail a procurement reconciliation. Order according to the exact prefix the Fortinet quote or price list specifies for your NGFW chassis.

Does the EdgeOptic FG-TRAN-SFP28-SR compatible require FortiOS CLI overrides to come up on a FortiGate?

EdgeOptic codes the FG-TRAN-SFP28-SR compatible with Fortinet-recognized EEPROM, so FortiGate chassis identify the module against the Fortinet transceiver validation list at the hardware-identification layer. The intent is that the module comes up on the 25G SFP28 port without a CLI override for vendor identification. FortiOS release-specific behaviour around transceiver acceptance can vary; for a specific FortiOS image and chassis combination, the FortiOS release notes and the chassis hardware guide are the authoritative sources.

What reach does the FG-TRAN-SFP28-SR cover on multimode fiber?

100m on OM4 and OM5 multimode fiber, 70m on OM3. The optical envelope is the standard 25GBASE-SR short-reach class: 5.3 dB link budget with host RS-FEC (IEEE 802.3by Clause 108), 850nm VCSEL, LC/UPC duplex. For spans beyond 100m, the FG-TRAN-SFP28-LR long-reach Fortinet SKU is the correct SFP28 part; FG-TRAN-SFP28-SR is deployment-scope-limited to in-rack and short inter-rack 25G links.
