Fortinet compatible FG-TRAN-SFP28-SR Description

EdgeOptic's FG-TRAN-SFP28-SR compatible is a Fortinet-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor SFP28 dual-rate 10G/25G SR transceiver. FG-TRAN-SFP28-SR is Fortinet's FG-prefixed ordering code for the 25GBASE-SR SFP28 specified against the FortiGate firewall range with 25G SFP28 interfaces. The module is programmed with Fortinet-recognized EEPROM vendor and part-number strings so the FortiGate platform reads the optic cleanly through the standard SFP28 management interface.

Optical behavior is 25GBASE-SR per IEEE 802.3by Clause 112 over duplex multi-mode fiber, with 10GBASE-SR support per IEEE 802.3ae on dual-rate SFP28 host ports. Line signaling rate is 10.3125 Gbps at 10GBASE-SR and 25.78125 Gbps at 25GBASE-SR. Reach is 100 m on OM4 or OM5 and 70 m on OM3, all within the SFP28 SerDes envelope defined by SFP28 MSA SFF-8402.

Optical path is 850 nm VCSEL transmitter, PIN photodiode receiver, TX optical power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget, LC/UPC duplex connector. Digital diagnostics are SFF-8472 compliant, exposing per-module temperature, supply voltage, TX bias, TX power and RX power through the FortiGate transceiver-diagnostics interface. Power dissipation is 0.3 W, the module is hot-swappable, and the operating temperature range is 0 to 70°C commercial.

FG-TRAN-SFP28-SR is the procurement SKU for the 25G SFP28 cages on FortiGate firewall platforms. Fortinet's catalog also lists FN-TRAN-SFP28-SR as an ordering code for the 25GBASE-SR optic under the FN- prefix range; FG-TRAN-SFP28-SR is the FortiGate-prefixed SKU for buyers whose Fortinet quote or BOM references the FG- prefix explicitly. For the FortiGate models in scope on a specific deployment, verify FG-TRAN-SFP28-SR against Fortinet's Supported Transceivers documentation for your FortiGate chassis and FortiOS release before specifying the part.

On FEC, 25G FEC mode is configured at the MAC layer on each link partner and the optical path is agnostic to whether RS-FEC per IEEE 802.3by Clause 108 or BASE-R FEC is negotiated on the host. The FortiGate FEC configuration determines the negotiated mode on the link; confirm the FEC profile on both link partners during commissioning to avoid mismatch on mixed-vendor 25G links. The module is symmetrically compatible with either FEC mode supported on the FortiGate host port.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For FortiGate firewall rollouts where FG-TRAN-SFP28-SR is the catalog SKU on the Fortinet quote, multi-site volume pricing on a 25G aggregation deployment, or compatibility verification against a specific FortiGate chassis and FortiOS release, contact our sales team.

Frequently Asked Questions

Is FG-TRAN-SFP28-SR the same optic as FN-TRAN-SFP28-SR, or are they different modules?

FG-TRAN-SFP28-SR and FN-TRAN-SFP28-SR are both Fortinet 25GBASE-SR SFP28 ordering codes. They share identical optical specifications as 25GBASE-SR modules operating to IEEE 802.3by Clause 112. Fortinet's Supported Transceivers documentation for your FortiGate model and FortiOS release is the authoritative source for which prefix your chassis accepts. The two SKUs are not interchangeable on a Fortinet quote because procurement and PO-matching require the exact SKU string from the Fortinet price list. Match the prefix to whichever SKU your Fortinet quote specifies.

Which FortiGate firewall models accept the FG-TRAN-SFP28-SR on their 25G SFP28 ports?

FG-TRAN-SFP28-SR is positioned against FortiGate firewall chassis that ship with 25G SFP28 cages. Verify FG-TRAN-SFP28-SR against Fortinet's Supported Transceivers documentation for your specific FortiGate model and FortiOS release before specifying the part; the supported-transceiver list varies by chassis SKU and FortiOS version, and Fortinet's documentation is the authoritative source for matching the optic to the platform. EdgeOptic's compatible carries Fortinet-recognized EEPROM vendor and part-number strings so the FortiGate platform reads the optic cleanly through the standard SFP28 management interface.

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

Fortinet does not publish a public transceiver override command for FortiGate third-party optic handling. A Fortinet-coded compatible module that presents Fortinet-recognized EEPROM vendor and part-number strings registers cleanly through the standard SFP28 management interface on FortiGate insertion without an admin override. Operators specifying a Fortinet-coded compatible should expect to handle module support through the compatible supplier rather than Fortinet TAC; the optical link to the link partner is governed by the IEEE 802.3by Clause 112 spec, not by FortiGate-side EEPROM.
