The fastest path to Tier-1 duplex and multi-fiber certification
Released in 2025, the pro version of PXM/LXM is more than a cutting-edge tool; it’s a game changer for Tier-1 fiber certification in data center networks. It handles the challenges of both duplex and multi-fiber testing, so it’s little wonder that the PXM/LXM sets new standards for speed and versatility. Its intuitive design helps empower contractors and data center technicians of all experience levels handling any size network to deliver accurate and reliable Tier-1 certifications with confidence.
The fastest
Measure loss, length, and polarity on duplex and multi-fiber links at two wavelengths in just 1 second.
Multi-connector compatibility
Switch within seconds between duplex and multi-fiber testing with patented Click-Out adapters, compatible with duplex MDC, SN, LC as well as MPO and SYSTIMAX MTP.
First-time-right polarity
The industry's only tester capable of detecting duplex and multi-fiber polarity issues hidden in trunk cabling, ensuring fibers are correctly connected before the network goes live.
Standards compliance
EXFO’s Click-Out adapters enable one-cord referencing for duplex and multi-fiber cabling, eliminating adapter cords to match pinned and unpinned gender types ensuring compliance with TIA, ISO, and IEC standards.

Switch between duplex and multi-fiber while ensuring standards compliance
EXFO’s patented Click-Out adapters allow quick, tool-free switching between duplex and multi-fiber testing. They support a wide range of connector types, including duplex MDC, SN, LC, as well as MPO, and SYSTIMAX MTP.
Enabling simplified one-cord referencing for standards-compliant certification, it delivers fast, versatile, and reliable testing for high-density fiber networks.
Testing beyond 12 fibers,
in just 1 second
In addition to native duplex and base-8/12 fiber testing, PXM/LXM enables testing of 16 or 24 fibers in just 1 second, using dual kits or a loopback method.
Test faster. Test more.
Being the world’s n.1 provider of fiber optic test solutions means we build in features that make testing more intuitive and efficient.
Large, hybrid contactless connector: PXM accommodates both APC and UPC connectors to support multimode and singlemode link testing. Large core detector allows the PXM to give precise measurements with low uncertainty.
Generate reports with FastReporter: PXM power meter measurements for power or loss can be processed directly by FastReporter.
Smartphone-grade touchscreen: PXM and LXM have integrated high‑quality capacitive color touchscreens designed to be visible in full sun or dark areas, from any angle.
