Fortinet compatible FG-TRAN-QSFP28-LR4 Description
EdgeOptic's FG-TRAN-QSFP28-LR4 compatible is a Fortinet-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. Fortinet's FortiSwitch-Compatible Transceivers documentation lists FG-TRAN-QSFP28-LR4 (manufacturer P/N FTLC1511RDPL) for FortiSwitch chassis with QSFP28 ports, and the same SKU is listed as compatible with FortiGate platforms with QSFP28 cages per third-party Fortinet reseller listings; verify the FG-TRAN-QSFP28-LR4 entry in your FortiGate platform's supported transceiver guide before deployment. The compatible ships with EEPROM data programmed for the FG-TRAN-QSFP28-LR4 ordering code, so Fortinet equipment identifies it as a vendor-supported optic without manual override.
The optical path uses LAN WDM with four channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, multiplexed onto a single duplex LC fiber pair. Each channel carries 25.78125 Gbps NRZ for an aggregate 103.125 Gbps line rate. Optical path loss budget is 6.3 dB per IEEE 802.3ba Clause 88, supporting up to 10 km over OS2 (G.652) single-mode fiber. The 6.3 dB budget covers a typical OS2 path at roughly 0.2 dB/km attenuation at 1310 nm plus connector loss in the order of 0.5 dB per LC-LC mating. Reach in the field depends on actual fiber attenuation and connector loss across the link.
Digital diagnostic monitoring (DDM/DOM) reports transmit and receive optical power, module temperature, laser bias current, and supply voltage through the SFF-8636 management interface. FortiOS surfaces these values through the FortiOS CLI and through the Network > Interfaces view in the GUI; FortiManager aggregates the same values across managed FortiGate and FortiSwitch devices, so optical link margin can be tracked centrally for each installed FG-TRAN-QSFP28-LR4 port. Host electrical interface is CAUI-4 (4x25G NRZ). Operating temperature is 0 to 70 degrees Celsius (commercial). Power draw is typical 3.5 W, within the QSFP28 Class 4 cage budget of 4.5 W maximum per SFF-8665.
The module is CE and RoHS certified and complies with QSFP28 MSA SFF-8665 and IEEE 802.3ba 100GBASE-LR4. Compatible with FortiGate platforms with QSFP28 cages and FortiSwitch chassis with QSFP28 ports; verify the FG-TRAN-QSFP28-LR4 entry in Fortinet's certified transceiver list for your specific chassis and FortiOS release before deployment. 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
What is the difference between FG-TRAN-QSFP28-LR4 and FN-TRAN-QSFP28-LR?
FG-TRAN-QSFP28-LR4 and FN-TRAN-QSFP28-LR are alternate Fortinet ordering codes for 100GBASE-LR4 QSFP28 transceivers with the same optical specification. Both appear in Fortinet's FortiSwitch-Compatible Transceivers documentation for FortiSwitch chassis, and both are supported on FortiGate platforms with QSFP28 cages. Match the SKU specified in your device's Fortinet transceiver list when ordering, since Fortinet equipment validates the EEPROM ordering code against the expected entry. If your deployment mixes FortiSwitch and FortiGate ports, confirm which code each chassis requires before ordering.
Which FortiGate models support the FG-TRAN-QSFP28-LR4?
FG-TRAN-QSFP28-LR4 is supported on FortiGate platforms equipped with QSFP28 cages. Specific model and FortiOS-release support varies, so verify the FG-TRAN-QSFP28-LR4 entry in Fortinet's certified transceiver list for your chassis before purchasing. For pre-purchase verification, contact our sales team with the FortiGate model and FortiOS release in use.
Does FortiOS display DDM values for the FG-TRAN-QSFP28-LR4 compatible?
Yes. FortiOS reads the SFF-8636 DDM/DOM fields from the QSFP28 module and surfaces transmit and receive optical power, module temperature, laser bias current, and supply voltage through the 'get system interface transceiver' CLI output and through Network > Interfaces in the GUI. FortiManager aggregates DDM data across managed FortiGate and FortiSwitch devices, so optical link margin can be tracked centrally for all installed FG-TRAN-QSFP28-LR4 modules.
Can the FG-TRAN-QSFP28-LR4 be used for FortiGate HA heartbeat links?
Yes, when the HA peers are physically separated and connected over single-mode fiber within the 10 km LR4 reach. Configure a dedicated heartbeat interface on the QSFP28 port and assign it to the HA cluster per Fortinet's HA documentation. Confirm the FG-TRAN-QSFP28-LR4 is listed in the supported transceiver table for the FortiOS release running on both peers, and verify FEC and DDM behavior on the heartbeat port matches the rest of the HA fabric.
