PLANEX FXG-05RPT2 5-Port Gigabit Repeater Hub / Network TAP - USB-C, switching hubs forward traffic only to the destination port, which isefficient but means a laptop plugged into a spare port sees nothing of whatthe other ports are doing. The FXG-05RPT2 is a repeater hub: every framereceived on one port is retransmitted to all the others. Connect a machinerunning a packet capture tool and you see the traffic on the whole segment,with no configuration, no management interface, and no port mirroring to setup.
True repeater hubs at gigabit speed have become very hard to find - thetechnology was superseded commercially, and dedicated network TAP hardwarecosts many times more. The previous generation FXG-05RPT, launched in 2013,became known among Japanese network engineers as an essential kit item. Thissuccessor replaces the metal case with resin, halving the weight to about 80g, and switches power input to USB Type-C at 5V, so it runs from a laptopport, a power bank, or any generic USB charger.

Also used as a portable field tool by networkengineers and integrators who need capture capability on site withoutreconfiguring customer NOTES FOR INTERNATIONAL VOLTAGE OR PLUG ISSUEThis unit is powered over USB Type-C at 5V and no AC adapter is supplied.There is no Japanese 100V mains adapter involved, so no transformer or plugadapter is required. Use any standard USB port, power bank, or USB charger.A USB charger is NOT included.
REPEATER OPERATION - PERFORMANCE CHARACTERISTICSA repeater hub operates as a single collision domain and forwards alltraffic to all ports. This is exactly what makes capture possible, and italso means the device is not a substitute for a switch in a productionnetwork. On a busy segment, expect collisions and reduced effectivethroughput. Use it as a diagnostic tool, not as permanent infrastructure.
CERTIFICATIONThis unit carries VCCI Class B certification for Japan. It does NOT carryFCC, CE, or UKCA marking. Buyers are responsible for confirming what applieswhere they are.
RESIN CASEThis generation uses a resin case rather than the metal case of the previousFXG-05RPT. This is what brings the weight down from about 160 g to about 80g. If you specifically require a metal enclosure, note the change.
ETHERNET CABLES NOT INCLUDEDNo LAN cables are supplied. Cat 5e or better is required for gigabitoperation.
LAWFUL USEThis is a network diagnostic tool. Capturing traffic on networks you do notown or are not authorised to monitor may be unlawful in your jurisdiction.Buyers are responsible for using the device lawfully.
JAPANESE DOMESTIC MODELThe packaging and manual are in Japanese only. The device requires noconfiguration and no Japanese to operate. Planex warranty and support arevalid in Japan only.
