Fortinet FN-TRAN-SFP+LR 10 GE SFP+ 10 km Transceiver

What FN-TRAN-SFP+LR is

FN-TRAN-SFP+LR is the Fortinet ordering code for a 10 GE SFP+ long-range optical module. The official Fortinet transceiver data sheet identifies this exact SKU as a 1310 nm module for single-mode fiber, with a duplex LC connector and a stated maximum reach of 10 km. Its specified operating temperature is 0 to 70 degrees C, and the ordering row marks it as TAA compliant.

Exact SKU boundaries

This SKU is the standard-temperature LR version. It is not FN-TRAN-SFP+LRI, which Fortinet lists with an industrial -40 to 85 degrees C range. It is also not FN-TRAN-SFP+LRM, whose official ordering row specifies a much shorter 220 m or 300 m reach and different fiber choices. These suffixes describe different orderable modules and should not be interchanged on a quotation.

Link-design checks before ordering

• Confirm that both target Fortinet systems support 10 GE operation in their SFP+ slots.
• Use single-mode fiber terminated with duplex LC connectors.
• Check the complete optical-loss budget; the 10 km figure is the manufacturer's maximum reach, not a guarantee for every installed route.
• Verify platform and software support for the exact host models at both ends.
• Select the LRI version instead when the environment requires the industrial temperature range documented for that separate SKU.

Acceptance record

Keep the ordered SKU, the two host models and ports, fiber type, connector type, route loss, wavelength, required temperature class, and link-test result together. This makes the purchase decision auditable and prevents a standard LR, industrial LRI, or shorter-reach LRM module from being received against the wrong design.
