Fortinet compatible FN-TRAN-QSFP28-DR Description
EdgeOptic's FN-TRAN-QSFP28-DR compatible is a Fortinet-coded version of the EdgeOptic 100G-QSFP28-SL500 multi-vendor 100GBASE-DR transceiver. It runs single-lambda 100G PAM4 at 1310nm over duplex single-mode fiber, IEEE 802.3cd 100GBASE-DR and 100G Lambda MSA compliant in a QSFP28 form factor. The module maps the four 25G NRZ host lanes to one 100G PAM4 optical wavelength, giving 106.25 Gbps line rate with a 3 dB link budget that covers 500m over G.652 SMF.
Transmit uses an EML laser across the 1304.5 to 1317.5nm range; receive uses a PIN photodiode. DOM diagnostics report live optical and temperature data, and the module operates across the standard 0 to 70 degrees C range with duplex LC connectors. RS(544,514) KP4 FEC runs inside the module DSP, so the host port must keep its own FEC disabled. On FortiGate platforms running FortiOS 7.6.1 and later, setting the interface mediatype to dr automatically disables host FEC, which matches this module's embedded-FEC design.
As a single-lambda DR module it interoperates with 400GBASE-DR4 optics over a fiber breakout, a common 400G-to-100G fan-out in data center links. Verify port and chassis support against Fortinet's transceiver compatibility documentation for your FortiGate model and FortiOS release.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Made to order with a 2-week lead time and a lifetime warranty included. For volume pricing or project requirements, contact our sales team.
Frequently Asked Questions
Does FN-TRAN-QSFP28-DR need set mediatype dr on a FortiGate?
On FortiGate platforms with 100G QSFP28 ports running FortiOS 7.6.1 and later, set the interface mediatype to dr for this module. FortiOS then disables host-side forward error correction automatically, which is the correct posture here: the module carries RS(544,514) KP4 FEC internally, so the host must not run its own. Older FortiOS releases may handle the setting differently, so confirm against Fortinet's documentation for your version.
Will a compatible FN-TRAN-QSFP28-DR trigger the transceiver not certified by Fortinet warning?
FortiGate flags non-OEM optics with a transceiver not certified by Fortinet message, and Fortinet provides no CLI command to bypass the certification check. EdgeOptic codes its Fortinet-compatible modules with Fortinet-recognized EEPROM to address this. Any residual warning depends on the FortiOS version and platform, so review the fix procedure in our Fortinet certification knowledge base article and verify against your FortiOS release.
