Tier-1 certifier for single and multi-mode fibers provides faster and right-first-time testing

QUEBEC CITY, May 8, 2023 — EXFO, the communications industry’s test, monitoring and analytics experts, today announced new capabilities in testing high-volume fibers in optical networks, delivering the fastest multi-fiber push-on (MPO) certification capability in the industry.

EXFO’s new PXM/LXM optical loss test set (OLTS) supporting multimode fibers—plus the addition of new certification features to its current PXM/LXM OLTS – are showcased today at the opening of Data Center World in Austin, Texas (EXFO booth # 926). These solutions are optimized for data centers and enterprise networks, which require certification based on industry standards of numerous single mode or multimode links.

“Testing a high volume of fibers is extremely time-consuming and represents a big challenge for technicians and contractors,” said Sophie Legault, Director Test and Measurement Network Deployment and Operations at EXFO. “With the PXM/LXM certification solution, we’ve combined the fastest loss measurement in the industry with an on-board analysis based on nearly 20 key industry standards, meeting our customer requirements to save time while doing the job right the first time.”

EXFO’s PXM now provides length measurement for both single and multimode fibers with on-board pass/fail diagnosis based on cabling and network application standards. It also includes the FasTesT feature, which provides loss per channel at the 2 selected wavelengths, as well as determining the length and polarity type of the link under test once continuity is detected. The LXM includes a fiber tracing feature that utilizes a visual fault locator (VFL) on the same port as the MPO source itself, which helps technicians on the other end find the MPO port to which they need to connect the PXM. The VFL also makes it easy to locate macrobends or breaks in the fiber.

Additional key features and benefits of EXFO’s PXM/LXM OLTS solutions include:

  • Hybrid contactless connector (PXM) that can accommodate both APC and UPC connectors, thus supporting multimode and singlemode link testing.
  • Exclusive to EXFO: Standard 3-year calibration interval and 3-year warranty to help reduce costs related to factory returns and downtime.
  • The PXM and LXM have integrated high‑quality capacitive color touchscreens designed to be visible in full sun or dark areas, from any angle.

The PXM/LXM OLTS for certification of single or multimode fibers is available now. For more information about EXFO’s PXM/LXM test solution, visit
