Fortinet SFP compatibility matrix by model and SKU

EON Technology validates Fortinet transceiver compatibility by model, firmware, port and optical part number. This page is a quick lookup reference by model and by SKU: if you need the step-by-step selection process, how to read the diagnostics and the project cases, see the transceiver recoding service for Fortinet.

Fortinet equipment families as the matrix axes

The matrix is organized by device, because each family exposes different ports and form factors. We cover the FortiGate line (60F, 100F, 200F, 400F, 600F, 1000F, 1800F and 3200F) and the FortiSwitch line (1xx, 2xx, 4xx and 5xx series). We keep FortiGate and FortiSwitch in separate tables because they are distinct compatibility documents and each one is looked up by its own set of ports.

FortiGate — validated platforms

FortiGate platform	Ports / form factor	Optics	Status
FortiGate 200F	SFP+ (10G) · SFP28 (25G)	SR/LR, MM/SM	Validated
FortiGate 600F	SFP+ (10G) · SFP28 (25G) · QSFP28 (100G)	SR/LR, SR4/LR4	Validated
FortiGate 1800F	SFP28 (25G) · QSFP28 (100G)	SR/LR, SR4/LR4	Validated

FortiSwitch — validated platforms

FortiSwitch platform	Ports / form factor	Optics	Status
Fortinet FortiSwitch 648F	SFP28 (25G) · QSFP28 (100G) uplinks	SR/LR, SR4/LR4	Validated
FortiSwitch 1048E	SFP+ (10G) · QSFP28 (100G) uplinks	SR/LR, SR4/LR4	Validated

Form factors and optics per cell

Form factor	Speed	Typical optics	Reach
SFP	1G	SX (MM 850 nm) · LX (SM 1310 nm) · SFP-T (RJ45 copper)	100 m copper · 550 m MM · 10 km SM
SFP+	10G	SR (MM 850 nm) · LR (SM 1310 nm) · ER (SM)	300 m MM · 10 km LR · 40 km ER
SFP28	25G	SR · LR	100 m MM · 10 km SM
QSFP+	40G	SR4 · LR4	150 m MM · 10 km SM
QSFP28	100G	SR4 · LR4 · BiDi	100 m MM · 10 km SM

Each cell combines form factor, wavelength and reach: multimode (MM) 850 nm for short runs and single-mode (SM) 1310/1550 nm for long distances, plus BiDi variants, SFP-T/RJ45 copper and DAC/AOC assemblies for stacking and uplinks. Use distance as a quick selection filter: up to 100 m on copper, 300 to 550 m on MM and 10 to 40 km on SM.

Cross-reference by SKU: from the Fortinet part number to the EON equivalent

Each FN-TRAN- and FG-TRAN- part number maps to its EON compatible equivalent with the same optics.

Fortinet SKU	Description	EON compatible equivalent
FN-TRAN-SX	1G SFP MM 850 nm	SFP 1G SX
FN-TRAN-LX	1G SFP SM 1310 nm	SFP 1G LX
FN-TRAN-GC	1G SFP RJ45 copper	SFP-T 1G copper
FN-TRAN-SFP+SR	10G SFP+ MM 850 nm	SFP+ 10G SR
FN-TRAN-SFP+LR	10G SFP+ SM 1310 nm	SFP+ 10G LR
FN-TRAN-QSFP+SR4	40G QSFP+ MM	QSFP+ 40G SR4
FN-TRAN-QSFP+LR4	40G QSFP+ SM	QSFP+ 40G LR4
FN-TRAN-QSFP28-SR4	100G QSFP28 MM	QSFP28 100G SR4

We cross-reference the OEM SKU directly to its equivalent, and we adapt and validate compatibility for the target platform. Need another part number? Browse the transceiver catalog or send us your bill of materials and we map it.

Firmware and operating mode as the validated status

We record the release on which each module was verified: FortiOS 7.0, 7.2 and 7.4 on FortiGate, and FortiSwitchOS on FortiSwitch, both in managed FortiLink mode and in standalone operation. Within a Security Fabric architecture, a FortiSwitch managed over FortiLink inherits the validation of the FortiGate that manages it, which is why firmware is a status column, not a secondary detail.

What to check before ordering

FortiOS exposes the list of supported transceivers and their DOM/DDM readings from the CLI and the GUI (following the Fortinet community Technical Tip). Before requesting, confirm three data points: the exact model and its firmware, the physical port type (SFP+, SFP28, QSFP+ or QSFP28) and the required optical part number (SR, LR, ER or copper). If your equipment needs adaptation, our Fortinet transceiver recoding service adapts and validates compatibility by model, firmware, port and optical part number. Typical dispatch in 48h*.

We serve projects on multivendor infrastructure. EON serves Latin America and Spain from a centralized operation in Colombia.

*Subject to inventory, destination country, carrier, customs, the customer’s import process and third-party logistics conditions.

Frequently asked questions — Fortinet compatibility

Which EON transceiver is equivalent to the Fortinet FN-TRAN-SFP+SR and FN-TRAN-SFP+LR?

The FN-TRAN-SFP+SR (10G SFP+ multimode, 850 nm, up to 300 m) and the FN-TRAN-SFP+LR (10G SFP+ single-mode, 1310 nm, up to 10 km) each have an EON compatible equivalent with the same optical part number. We cross-reference the OEM SKU directly to its equivalent and validate compatibility by model, firmware, port and optical part number before dispatch.

Which SFP+/QSFP modules does each model accept? For example, a FortiGate 200F versus a FortiGate 600F or a FortiSwitch 248E.

It depends on the physical ports of each platform: the FortiGate 200F exposes SFP+ (10G) and SFP28 (25G) ports; the FortiGate 600F adds QSFP28 (100G) cages; and the FortiSwitch 248E combines 1G copper with SFP+ uplinks. It is a lookup by model, not a generic recommendation, and we validate compatibility by model, firmware, port and optical part number.

What is the difference between the Fortinet FN-TRAN and FG-TRAN naming conventions, and how do I read the matrix?

They are Fortinet SKU conventions: the FN-TRAN- family groups most optical and copper transceivers in the catalog, while FG-TRAN- appears on part numbers associated with certain FortiGate equipment. Each part number is read by form factor, speed and optics (SR/LR/ER) and cross-referenced to its EON compatible equivalent, whose compatibility we validate by model, firmware, port and optical part number.

What do I do if FortiOS shows the transceiver as 'unknown' or does not recognize it?

First check that the equipment model and the FortiOS release match the matrix row: a correct module on a firmware release not yet covered can show as 'unknown'. If the hardware is compatible but the platform requires a specific identifier, the transceiver recoding service adapts and validates the module's compatibility for your FortiGate or FortiSwitch, with 90-day service coverage under the agreed conditions. The full port diagnostic is covered on the Fortinet transceiver recoding page.

Where do I check the list of transceivers supported by a FortiGate from the CLI or the GUI?

FortiOS exposes the list of supported transceivers and their DOM/DDM readings from both the CLI and the GUI, following the Technical Tip published by the Fortinet community. It is a different check from the port diagnostic explained step by step on the recoding page; here it is enough to confirm that the module shows as recognized and with optical power within range. We validate compatibility by model, firmware, port and optical part number.
