Fortinet compatible FN-TRAN-QSFP28-CWDM4 Description

EdgeOptic's FN-TRAN-QSFP28-CWDM4 compatible is a Fortinet-coded CWDM4 QSFP28 version of the EdgeOptic 100G-QSFP28-2.1 multi-vendor 100G CWDM4 2km transceiver. Fortinet documents the OEM optic as the standard 100 GE QSFP28 CWDM4 module for systems with QSFP28 slots, supplied across the FortiGate next-generation firewall portfolio and the FortiSwitch chassis range with QSFP28 ports.

The module runs four CWDM channels on the 1271, 1291, 1311, and 1331 nm wavelength plan defined by the CWDM4 MSA and ITU-T G.694.2, with NRZ modulation across each lane. Output uses a duplex LC connector and supports 2 km links over G.652 single-mode fibre. The optical front end uses DML transmitters and PIN receivers, with host-side FEC supported per the CWDM4 MSA Technical Specification. Operating temperature spans the commercial 0 to 70 °C range.

The FN-TRAN-QSFP28-CWDM4 covers 100 Gigabit Ethernet on FortiGate and FortiSwitch security appliances, which operate as Ethernet-only platforms at the QSFP28 cage. The EdgeOptic 100G-QSFP28-2.1 family additionally supports OTU4 (112 Gbps) and 4x32G Fibre Channel (112.2 Gbps) variants for OTN transport and SAN deployments on platforms that carry those framers. Those rates ship as separate part numbers and target router or storage chassis rather than NGFW appliances, so for OTU4 or Fibre Channel coding contact our sales team.

Fortinet lists FN-TRAN-QSFP28-CWDM4 as the CWDM4 2km QSFP28 option for the FortiGate 3000 family (3400E, 3401E, 3600E, 3601E, 3960E, 3980E), the FortiGate 7030E-QSFP28 chassis, and FortiSwitch 1000 series chassis fitted with QSFP28 cages. Engineers using 100G uplinks between FortiGate clusters or peering NGFW edges to upstream 100G switching gear cover the 2 km span over a single fibre pair with this optic on both ends.

EdgeOptic codes the FN-TRAN-QSFP28-CWDM4 compatible with Fortinet-recognized EEPROM, so FortiOS accepts the module on the interface without the third-party transceiver warning that appears for non-coded optics in the FortiGate GUI. The EEPROM identifies the optic against the FN-TRAN-QSFP28-CWDM4 part number, so chassis inventory and SNMP transceiver tables report the module consistently with Fortinet OEM stock.

Digital diagnostics (DDM/DOM) report TX power, RX power, bias current, supply voltage, and temperature per SFF-8636. The module is QSFP28 MSA SFF-8665 compliant and aligned with the CWDM4 MSA Technical Specification.

Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty.

Frequently Asked Questions

Will a third-party FN-TRAN-QSFP28-CWDM4 compatible cause a 'not certified by Fortinet' warning on FortiGate?

EdgeOptic's FN-TRAN-QSFP28-CWDM4 compatible is coded with Fortinet-recognized EEPROM, so FortiOS initializes the module without the 'transceiver not certified by Fortinet' notice that appears in the GUI and CLI for non-Fortinet-coded third-party optics. The interface comes up under standard transceiver registration and the chassis inventory reports the part number consistently with Fortinet OEM stock.
