Overview
The Ubiquiti UACC-LRE is a long-range Gigabit Ethernet repeater designed to extend Ethernet and PoE connections beyond the normal reach of a single copper cable run. It provides two Gigabit Ethernet RJ45 ports, receives power through PoE or PoE+, and passes PoE power through to a connected downstream device.
Network and PoE Operation
The UACC-LRE provides a 2 Gbps total non-blocking line rate, 4 Gbps switching capacity, and a forwarding rate of 1.488 Mpps. Its PoE input operates over two pairs using pins 1, 2+ and 3, 6-, while the downstream port provides passthrough PoE using the same two-pair arrangement.
Ubiquiti specifies up to 22.5 W of available downstream PoE power and a 1.5 W maximum power consumption for the repeater itself, excluding PoE output. The supported PoE input voltage range is 37–57 V DC.
Deployment
Multiple UACC-LRE repeaters can be used to extend PoE Ethernet connections over longer cable routes. Ubiquiti specifies extension of PoE connections up to 1 km when repeaters are placed in 100 m increments.
Compatibility and Installation Considerations
The UACC-LRE uses two Gigabit RJ45 interfaces and does not require network configuration. Its PoE input uses a two-pair power arrangement, and Ubiquiti notes that this powering method may not be supported by certain third-party switches. A compatible PoE source is therefore required for deployment.
Key Features
- Two Gigabit Ethernet RJ45 ports for network connectivity and PoE passthrough.
- Up to 22.5 W of available downstream PoE power.
- Up to 1 km PoE connection extension when repeaters are installed in 100 m increments.
- 10 kA+ discharge protection with ±30 kV air/contact ESD/EMP protection.
- IPX5 weatherproof enclosure with an operating temperature range of -40 to 80 °C.
DC Supplies Product Note
For long cable runs, the spacing of repeaters is an important deployment consideration: Ubiquiti specifies 100 m increments for achieving the stated extension distance. The upstream PoE source must also support the UACC-LRE's two-pair PoE input arrangement, particularly when using third-party switching equipment.

Frequently Asked Questions
What is the Ubiquiti UACC-LRE used for?
The UACC-LRE is used to extend Gigabit Ethernet and PoE connections over longer copper cable routes while providing downstream PoE passthrough.
How far can the UACC-LRE extend a PoE connection?
Ubiquiti specifies extension of PoE connections up to 1 km when repeaters are placed in 100 m increments.
How much PoE power can the UACC-LRE provide to a downstream device?
The UACC-LRE provides up to 22.5 W of available downstream PoE power.
Does the UACC-LRE require network configuration?
