Ubiquiti Networks continues to disrupt the wireless broadband market with revolutionary technology at breakthrough pricing, by introducing the airFiber® AF‑11FX, a radio purpose-built for outdoor PtP bridging and carrier-class network backhauls using the licensed 11 GHz radio band.
The AF‑11FX breaks free from the congested 5 GHz band to help meet the growing need for broadband capacity.
For maximum flexibility, the airFiber AF‑11FX works with the Ubiquiti® AF-11G35 antenna, or with most third-party antennas using an optional adapter kit (not

Groundbreaking Design
The AF-11FX gives exceptional performance compared to other 11 GHz radios in its price range. Unlike other products that use adaptations of Wi-Fi-based
designs, the AF-11FX is specially engineered for the 11 GHz band, with a custom modem and radio design that are optimized for the efficient transport of data. Specific advantages of the AF‑11FX include: True Full-Duplex Design, Ultra-Low Latency, Enhanced Robustness, Extended Range...

Channel Configuration
The airFiber AF‑11FX can use single (SISO) or bonded (MIMO)*channels, depending on your specific licensing requirements. The AF‑11FX also features different channel width sizes to suit your deployment needs, and you can independently configure TX and RX channel frequencies.
Reconfigurable Duplexers
The AF-11FX features a unique modular duplexer design to suit multiple frequency configurations.
Each AF-11FX radio can be configured to support any allowable frequency by simply changing the duplexers for high‑band or low‑band use in the 10.7 - 11.7 GHz allocation.

Each duplexer has a low channel and a high channel that can be configured by simply reversing the position of the duplexer.
Low-Band Duplexer: Low Channel 10.700 - 10.955 GHz, High Channel 11.200 - 11.445 GHz, Model - AF-11FX-L
High-Band Duplexer: Low Channel 10.940 - 11.200 GHz, High Channel 11.440 - 11.700 GHz, Model - AF-11FX-H

Highest Performance Value
The compact AF-11FX supports high-order constellations – up to 1024QAM – allowing it to deliver the greatest spectral efficiency in its class.

Ubiquiti’s INVICTUS™ 2 custom silicon and proprietary radio architecture are designed specifically for long-distance, outdoor wireless applications, providing superior performance, long-range capability, and higher delivered throughput.

Deployment Flexibility
The airFiber AF-11FX provides a number of deployment options including:
Power Source Options
Support for PoE or DC power gives you the flexibility to power the AF-11FX separately from Ethernet traffic.
• PoE power can be supplied on the DATA port, using the provided PoE adapter.
• DC power can be supplied using the terminal block.
Versatile, Ruggedized N-Type Connectors
N-connectors allow the AF‑11FX to be used with either the Ubiquiti AF‑11G35 antenna or a variety of commonly available antennas.
Specially designed silicone boots provide a weatherproof barrier against dust and moisture.

Model AF-11FX-H comes with one High Band Duplexer, for MIMO wireless mode second High Band Duplexer must be purchased.
