About the FN-TRAN-GC
The Fortinet FN-TRAN-GC copper transceiver provides flexible twisted pair connectivity by adapting an SFP slot into an 8-pin RJ-45 modular interface. It delivers 1000Mbps throughput up to 100 meters, making it practical for connecting copper patch panels, out-of-band management switches, and local WAN modems to FortiGate firewalls.
Compatibility
Compatible with Fortinet FortiGate 60F, 70F, 80F, 100E, 100F, 200F, 400F, 600F, and FortiSwitch models equipped with SFP ports. It allows administrators to expand RJ-45 copper port count without deploying external interface media converters or dedicated expansion switches.
How to identify a genuine unit
Housed in a sturdy metal SFP casing featuring an integrated RJ-45 modular socket with a spring release latch mechanism. The top label bears the Fortinet brand identifier, part number FN-TRAN-GC, manufacturing serial barcode, and international regulatory compliance markings.
Buying used
Inspect internal RJ-45 contact pins for bending, oxidation, or debris. Insert the transceiver into a FortiGate SFP port, connect a patch cable, and verify that auto-negotiation reliably synchronizes at 1000BASE-T full duplex with clean packet transmission statistics.
