Ubiquiti airFiber NxN Scalable MIMO Multiplexer MPx4
The Ubiquiti airFiber NxN MPx4 is a MIMO multiplexer that increases the throughput of airFiber links by up to 400%, while simultaneously establishing redundancy without the need of additional antennas.
Ubiquiti airFiber NxN MPx4 Key Features
4x4 MIMO Backhaul Technology
Multiplex (2) airFiber 5X radios*
• Aggregate Throughput up to 1+ Gbps
• Up to 1 Redundant Link
The AF-MPx4 is a scalable MIMO multiplexer that combines multiple airFiber X radios on a single dish antenna for superior noise immunity performance, redundancy, and multi-Gigabit throughput.

The airFiber NXN uses a common GPS timing reference meaning the radios work cohesively to deliver powerful, multi-Gigabit bridging performance for PtP links.
You can use multiple channels—even adjacent channels with no guard band—and place them anywhere within the radio band. Depending on model, either 2 or 4 airFiber X units can be mounted.

Multiple airFiber X radios mounted on a single dish antenna maximizes throughput and capacity in a clean, compact tower footprint, minimizing tower costs. For instance, the AF‑MPx8 consolidates four airFiber X dish antennas into one dish, or replaces up to 8+ non-airFiber links.
