How to identify a genuine unit
Enclosed in a compact SFP metallic casing with a black optical extraction latch bail indicating 850nm multimode operation. The top label bears the Fortinet brand name, model number FN-TRAN-SX, manufacturing serial number barcode, and optical safety compliance information.
Buying used
Inspect the optical bore with a fiber microscope to verify that the lens surfaces are free of contaminants or scratch marks. Seat the module in a live FortiGate port to verify that FortiOS detects the transceiver and reports link status at 1000Mbps full duplex.
