Overview
The Ubiquiti AF-MPX4-US is an airFiber 4x4 MIMO multiplexer designed to combine two compatible airFiber X radios on a single dish antenna. It provides 4x4 MIMO operation while allowing multiple radio channels to share one antenna system.
MIMO and Throughput
The AF-MPX4-US multiplexes two airFiber X radios using two 2x2 MIMO paths to create a 4x4 MIMO configuration. The platform supports aggregate throughput of more than 1 Gbps and up to one redundant link when deployed with compatible radios and network equipment.
Radio Compatibility
The AF-MPX4 is designed for compatible airFiber X radios, including the AF-5X and AF-4X according to Ubiquiti documentation. The multiplexer provides two weatherproof RP-SMA connectors for the radio channels and four additional weatherproof RP-SMA antenna connectors.
Installation
The unit is compatible with airFiber X and Rocket mounting systems and is designed to mount multiple radios to a single compatible dish antenna. The multiplexer helps consolidate the radio installation footprint while supporting multi-radio point-to-point wireless backhaul deployments.
Key Features
- 4x4 MIMO configuration using two 2x2 radio paths
- Multiplexes two compatible airFiber X radios
- Aggregate throughput up to 1+ Gbps
- Supports up to one redundant link
- Weatherproof RP-SMA RF connectors and airFiber X/Rocket mounting compatibility
Applications
The AF-MPX4-US is intended for high-capacity point-to-point wireless backhaul installations where multiple airFiber X radios need to operate through a shared compatible dish antenna. It can also be used where additional radio paths are required for capacity or link redundancy.
DC Supplies Product Note
The AF-MPX4-US is a radio multiplexer rather than a standalone wireless radio. Compatible airFiber X radios and a suitable antenna are required for a complete wireless link deployment.
