Add a 1 Gigabit Ethernet optical uplink or interconnect over single-mode fiber where copper distance limits do not apply. Fortinet FN-TRAN-LX is a 1000BASE-LX small form-factor pluggable transceiver with 1,310 nm optics, a duplex LC optical interface, and support for fiber reaches up to 10 km. Its SFP form factor installs into a compatible SFP slot, providing a removable optical interface rather than a fixed fiber port. Use this transceiver for point-to-point Gigabit links between network rooms, building distribution points, or remote equipment locations served by single-mode fiber. The duplex LC interface requires a two-fiber connection: one strand transmits and the other receives. Matching LX optics at the far end of the link maintain the 1 Gigabit Ethernet optical path across the installed single-mode cable plant. This specific optic is the LX member of a 1 Gigabit SFP range, distinguished by its long-wavelength 1,310 nm optical operation and single-mode fiber reach. It is intended for 1000BASE-LX connections rather than short-reach multimode-only links or higher-speed Ethernet uplinks. Select it when the connected device has an available compatible SFP port and the installed link requires a duplex LC, single-mode Gigabit connection.
