Fortinet compatible FN-TRAN-QSFP28-LR Description
EdgeOptic's FN-TRAN-QSFP28-LR compatible is a Fortinet-coded 100GBASE-LR4 QSFP28 transceiver built on the EdgeOptic 100G-QSFP28-10 platform. Fortinet's FortiSwitch-Compatible Transceivers documentation lists FN-TRAN-QSFP28-LR for FortiSwitch chassis with QSFP28 ports, and the same SKU is listed as compatible with FortiGate platforms with QSFP28 cages, including the FortiGate 3400, 3600, 3960, 3980, and 7030E series per publicly available Fortinet reseller listings; verify in your platform's supported transceiver list before ordering. The compatible ships with EEPROM data programmed for the FN-TRAN-QSFP28-LR ordering code, so Fortinet equipment identifies it as a vendor-supported optic without manual override. When ordering, confirm the required part number in your platform's transceiver compatibility list, since Fortinet offers both FN-TRAN and FG-TRAN variants of the 100GBASE-LR4 QSFP28 specification.
The optical path uses LAN WDM with four channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, multiplexed within the 1310 nm window 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.D) single-mode fiber. Reach in the field depends on actual fiber attenuation and connector loss.
Digital optical monitoring (DDM/DOM) reports transmit and receive optical power, module temperature, laser bias current, and supply voltage through the SFF-8636 management interface. The module has no internal FEC; it is transparent to host-side RS-FEC running in the host ASIC. Host electrical interface is CAUI-4 (4x25G NRZ). Operating temperature is 0 to 70 degrees Celsius (commercial). FN-TRAN-QSFP28-LR-I is a separate Fortinet industrial-temperature SKU (-40 to 85 degrees Celsius) and is not the same product. Power draw is typical 3.5 W; QSFP28 Class 4 cage budget is 4.5 W maximum per SFF-8665.
The module ships CE/RoHS certified and complies with QSFP28 MSA SFF-8665 and IEEE 802.3ba 100GBASE-LR4. Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For project-quantity pricing or alternative vendor coding, contact our sales team.
Frequently Asked Questions
What is the difference between FN-TRAN-QSFP28-LR and FG-TRAN-QSFP28-LR4?
FN-TRAN-QSFP28-LR and FG-TRAN-QSFP28-LR4 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 with QSFP28 ports. FN-TRAN-QSFP28-LR is also listed for FortiGate platforms with QSFP28 cages, including the FortiGate 3400, 3600, 3960, 3980, and 7030E series per publicly available Fortinet reseller listings. 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 Fortinet platforms support FN-TRAN-QSFP28-LR?
FN-TRAN-QSFP28-LR is listed in Fortinet's FortiSwitch-Compatible Transceivers documentation for FortiSwitch platforms with QSFP28 ports, and is listed as compatible with FortiGate platforms with QSFP28 cages, including the FortiGate 3400, 3600, 3960, 3980, and 7030E series per publicly available Fortinet reseller listings. Specific model and FortiOS-release support varies, so verify the FN-TRAN-QSFP28-LR entry in your chassis transceiver compatibility list and FortiOS release notes before deployment. For pre-purchase verification, contact our sales team with the Fortinet platform model and FortiOS release in use.
Does the compatible FN-TRAN-QSFP28-LR work natively on Fortinet equipment?
Yes. EdgeOptic codes the EEPROM with Fortinet-recognised FN-TRAN-QSFP28-LR data, so Fortinet platforms identify the module as a vendor-supported transceiver. No CLI override or third-party-optic configuration is required.
Is there an industrial-temperature variant of FN-TRAN-QSFP28-LR?
Yes. Fortinet sells FN-TRAN-QSFP28-LR-I as a separate industrial-temperature SKU rated -40 to 85 degrees Celsius. EdgeOptic's compatible covered on this page is the commercial-temperature equivalent (0 to 70 degrees Celsius). The two are not interchangeable for outdoor or extended-temperature deployments. Contact sales if you need the industrial variant coded for Fortinet.
