EXFO PXM/LXM - Duplex and Multi-Fibre OLTS

The EXFO PXM/LXM Optical Loss Test Set (OLTS) is a cutting-edge solution for tier-1 certification of duplex and multi-fibre links, including MPO-8, MPO-12, MPO-16, and MPO-24. Built for speed, accuracy, and ease of use, it delivers insertion loss, length, and polarity results at two wavelengths in just one second using EXFO’s FasTesT™ technology.

Ideal for hyperscale data centres, AI clusters, enterprise networks, and private infrastructure, the PXM (power meter) and LXM (light source) combo is designed for fast, error-free MPO and duplex fibre testing. With click-out adapter support, in-line VFL, and a 4-inch colour touchscreen, it simplifies even the most complex cabling validation tasks.

Key Features:

• Fastest test speed in the industry – results in 1 second at two wavelengths
• FasTesT™ technology – simultaneous insertion loss, polarity, and length measurements
• Supports multi-fibre and duplex testing – MPO-8, 12, 16, 24 and duplex LC, SN, MDC
• Click-out adapters – easily switch between connector types
• Inline VFL (Visual Fault Locator) – integrated into LXM light source for fault tracing
• Touchscreen interface – intuitive 4” display visible in all lighting conditions
• 3-year calibration and warranty – designed for long-term field reliability
• Field-replaceable battery and adapters – reduces downtime and total cost of ownership
• Smart reporting via FastReporter – simple export and documentation
• Polarity type detection – A, B, C or U (duplex and multi-fibre)

Applications:

• Data centre multi-fibre certification
• MPO cabling validation for 40G, 100G, 200G, 400G Ethernet
• FTTx and high-speed enterprise backbone testing
• AI and hyperscale infrastructure deployment
• End-to-end fibre link certification and maintenance
