The MikroTik GPeRx4 is a Gigabit Passive Ethernet Repeater designed to extend Ethernet and PoE connections over longer cable distances. It can be installed between compatible network devices to regenerate the Ethernet connection while allowing PoE power to pass through to connected equipment. The device features Gigabit Ethernet connectivity and is designed for use with compatible PoE-powered network installations. Its compact outdoor enclosure allows installation in network deployments where additional Ethernet cable distance is required. The MikroTik GPeRx4 is also identified by the new part number GPER14i. GPeRx4 and GPER14i refer to the same MikroTik product, with GPER14i representing the updated part number designation. The device does not require a separate power supply when used in a compatible PoE installation, as power is received and passed through the Ethernet connection.
