MPX-1A Encircled Flux Meter

The MPX-1A Encircled Flux Meter by Arden Photonics is a next-generation measurement solution designed to deliver precise, repeatable, and standards-compliant Encircled Flux (EF) measurements for multimode fiber optic systems. Trusted by industry leaders around the world, the MPX-1A has established itself as the benchmark for accurate modal launch condition analysis, helping organizations validate network performance, optimize optical system efficiency, and ensure compliance with internationally recognized testing standards.

Encircled Flux measurement plays a critical role in the characterization of multimode fiber networks. By accurately assessing the spatial distribution of light within a fiber, engineers can verify source performance, improve measurement consistency, and reduce uncertainty in network testing. The MPX-1A streamlines this process by providing automated, real-time measurements that remove many of the complexities associated with traditional EF testing methods.

Designed for both laboratory and production environments, the instrument enables users to simply connect a source and patchcord and immediately begin monitoring modal launch conditions. Advanced CMOS camera technology, combined with integrated auto-focus and auto-exposure capabilities, delivers highly accurate results while reducing operator dependency. This ensures that measurements remain consistent across different users, locations, and testing scenarios.

Whether you are validating multimode network infrastructure, characterizing optical sources, or working to meet IEC, IEEE, and aerospace requirements, the MPX-1A provides the confidence and reliability required for today's demanding fiber optic applications. Its combination of automation, accuracy, and compliance makes it an essential tool for organizations focused on maintaining the highest standards of optical performance.
