Fortinet compatible FN-TRAN-SFP28-SR Description
EdgeOptic's FN-TRAN-SFP28-SR compatible is a Fortinet-coded version of the EdgeOptic 25G-SFP28-100 multi-vendor 25GBASE-SR SFP28 transceiver. FN-TRAN is Fortinet's current transceiver SKU prefix; the earlier FortiGate-specific FG-TRAN and FortiSwitch-specific FS-TRAN families preceded it. The FN-TRAN-SFP28-SR is Fortinet's 25GE SFP28 short-reach module for FortiGate firewalls and FortiSwitch platforms with 25G SFP28 ports.
Optical specs: 850 nm VCSEL transmitter, PIN photodiode receiver, TX power −5 to +2.4 dBm, RX sensitivity better than −10.3 dBm, 5.3 dB link budget. Reach is 100 m on OM4, 100 m on OM5, and 70 m on OM3 with an LC/UPC duplex connector. The module is IEEE 802.3by Clause 112 compliant. RS-FEC per Clause 91 (RS(528,514)) is supported and enabled by the host port when 25GBASE-SR is negotiated.
Electrical interface follows SFF-8431 and SFF-8432 for the SFP28 cage. Digital diagnostics are SFF-8472 compliant for per-module temperature, supply voltage, TX bias, TX power, and RX power. DOM telemetry is readable through FortiOS and FortiSwitchOS management interfaces; consult the Fortinet admin guide for the command syntax matching the active firmware version. Power dissipation is 0.3 W and the module operates across 0 to 70 C.
FortiOS and FortiSwitchOS accept third-party transceivers only when the module presents correct Fortinet-recognized EEPROM coding; otherwise the platform raises a 'transceiver not certified by Fortinet' error. EdgeOptic programs the FN-TRAN-SFP28-SR with Fortinet-recognized EEPROM, so the module is accepted at link-up on FortiGate 25G SFP28 ports and on FortiSwitch 25G SFP28 uplinks. The unified FN-TRAN identity means the same physical module spares both the FortiGate and FortiSwitch fleet. For per-model qualification, consult the Fortinet FortiSwitch Compatible Transceivers document at docs.fortinet.com.
For legacy FortiGate populations still keyed to the FG-TRAN-SFP28-SR part number, EdgeOptic maintains a separate compatible product page. For bulk requirements or mixed FG-TRAN / FN-TRAN populations, contact our sales team. Ships next business day from EU stock with a lifetime warranty. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms.
Frequently Asked Questions
Does the FN-TRAN-SFP28-SR work on both FortiGate and FortiSwitch platforms?
Yes. FN-TRAN is Fortinet's current transceiver SKU prefix; the earlier FortiGate-specific FG-TRAN and FortiSwitch-specific FS-TRAN prefixes preceded it. The FN-TRAN-SFP28-SR operates on FortiGate firewalls with 25G SFP28 ports and on FortiSwitch platforms with 25G SFP28 uplinks using the same physical module. For specific FortiGate or FortiSwitch model qualification, consult the Fortinet FortiSwitch Compatible Transceivers document at docs.fortinet.com.
Does FortiOS require Fortinet-coded EEPROM to accept a third-party FN-TRAN-SFP28-SR?
Yes. FortiOS and FortiSwitchOS will raise a 'transceiver not certified by Fortinet' error if a module presents non-Fortinet EEPROM. EdgeOptic's FN-TRAN-SFP28-SR is programmed with Fortinet-recognized identification so the module is accepted at link-up and does not generate the unsupported-SFP event on syslog. Fortinet does not publish a supported CLI override for the EEPROM check, so correct vendor coding is the practical path to clean acceptance.
How is the FN-TRAN-SFP28-SR different from the older FG-TRAN-SFP28-SR?
FG-TRAN-SFP28-SR was the FortiGate-specific 25GE SFP28 SR transceiver SKU before Fortinet consolidated naming under the FN-TRAN prefix. The FN-TRAN-SFP28-SR is the current Fortinet 25G SR SFP28 module covering both FortiGate and FortiSwitch platforms. For legacy FortiGate fleets still ordering against the FG-TRAN-SFP28-SR part number, EdgeOptic maintains a separate FG-TRAN-SFP28-SR compatible page.
