Ubiquiti airFiber, airFiber 2X 5.1 - 2.4GHz, 500Mbps+ 200+km Radio Backhaul


The airFiber®2X.

The airFiber® X features up to 17.1 Mbps/MHz of industry-leading spectral efficiency and uses proprietary Hybrid Division Duplexing technology to achieve the highest TDD throughput available for long-range, PtP links.

Engineered for Performance
Ubiquiti’s INVICTUS™ custom silicon and proprietary radio architecture are designed specifically for long-distance, outdoor wireless applications.

Deployment Flexibility
The compact form factor allows the airFiber X to be used with airFiber Slant 45 antennas, or instantly upgrade a 2 GHz Rocket™link that uses a RocketDish™RD‑5G30/RD‑5G34* antenna.

Carrier Backhaul for the World
Deploy the 2.4, 3, 4, 5 or 11 GHz model that meets your specific spectrum requirements, anywhere around the world. The airFiber X features multiple channel width options to suit your deployment needs – up to 11 different channel sizes available for the AF-2X or AF-3X.

Optimal Operation and Channel Configuration
Channel width flexibility allows you to independently configure TX and RX channel frequencies and place them anywhere within the radio band to avoid local interference. You also have the ability to program different uplink and downlink duty cycles to support asymmetric traffic requirements.
