Your 10-Gigabit Air Bridge: Fiber Speed Without Trenching
With the UniFi Building-to-Building Bridge XG (UBB-XG), you can create an extremely high-performance Network bridge between two locations up to 500 meters apart. This system is the perfect alternative to a fiber optic connection between buildings when physical Cabling is not possible. Thanks to the 10G SFP+ port and a wireless performance of 6 GBit/s in the 60 GHz band, you can expand your 10-Gigabit backbone seamlessly and without compromise. Ideal for connecting company buildings, warehouses, or for fast backups between locations.
Maximum Reliability: The Dual-Radio Failover System
What happens in extreme heavy rain or dense fog? While other 60 GHz systems reach their limits here, the UBB-XG plays to its greatest strength. The integrated 5 GHz radio module (802.11ac) serves as an automatic failover. As soon as the primary connection is attenuated by weather conditions, the system seamlessly switches to the more robust 5 GHz connection. This keeps your Network online, even if the bandwidth is temporarily reduced. Your experience with UBB-XG range in rain will thus be characterized by maximum availability.
Perfectly Integrated: Effortless Management in the UniFi Ecosystem
If you already rely on the UniFi system from Ubiquiti, the UBB-XG is the logical choice. Forget complicated standalone solutions with separate management software. The bridge is managed centrally via the UniFi Network Controller, just like any other UniFi Access Point or UniFi Switch. This allows for simple configuration, detailed monitoring, and straightforward firmware updates – all from a single, familiar interface. This makes the decision to buy UBB-XG for company network expansion a simple and efficient one.
Built for Professionals: Installation and Robustness of the UBB-XG
The UBB-XG is designed for permanent outdoor use. The housing, made of an aluminum alloy and UV-stabilized polycarbonate, is IPX6 certified and withstands temperatures from -40 to 55 °C. Installation is significantly simplified by the included precision pole mount and the integrated LED status indicator. This visual aid allows for exact alignment of the two units for maximum signal strength, making the UniFi building bridge XG installation guide easy to follow in practice.

Frequently Asked Questions (FAQ)
Can the Ubiquiti UBB-XG be operated beyond its maximum range of 500 meters?
Ubiquiti officially specifies the maximum range as 500 meters. Operation beyond this distance is not recommended and will likely result in an unstable or non-functional connection, especially with the sensitive 60 GHz frequency.
Do I need two separate cables for power and the 10G data connection?
Yes. The 1 GbE RJ45 port is used for power via PoE++ and for management. The 10G SFP+ port is exclusively for data transmission and does not supply power. Therefore, for full speed, an Ethernet Cable for PoE and a fiber optic or DAC Cable for data must be run to each bridge point.
What happens to the connection during heavy rain or fog?
The 60 GHz frequency is susceptible to attenuation from heavy precipitation ('Rain Fade'). The UBB-XG compensates for this with an automatic failover to the more stable 5 GHz radio link. This maintains the network connection, albeit with a reduced bandwidth of up to 867 Mbps, until the 60 GHz link is fully available again.
Is the UBB-XG compatible with the standard Ubiquiti UBB?
No, the UBB-XG and the standard UBB are not compatible with each other. A wireless bridge must always consist of two identical devices. The UBB-XG is sold as a pre-configured pair to ensure smooth commissioning.
How do I precisely align the two bridge units with each other?
The UBB-XG has an integrated LED ring indicator that serves as a visual alignment tool. After rough mounting, an alignment mode can be activated via the UniFi Network App. The color and pattern of the LEDs then indicate the signal quality, allowing for fine-tuning for the best possible performance.
Can I operate the UBB-XG without a UniFi Controller (e.g., Cloud Key)?
Yes, a basic 'standalone' operation is possible. The devices can be paired with each other without a controller to establish a simple point-to-point connection. However, advanced configuration options, monitoring, and firmware updates are only available through the UniFi Network Controller, which is why operation with a controller is strongly recommended.
