iOLM – Turn All Your Techs into Experts Watch Now

iOLM—Go beyond OTDR Testing

Innovation is front and center at EXFO, and the intelligent Optical Link Mapper (iOLM) is a prime example of a game-changing solution. The iOLM lets you take advantage of the full power of your OTDR, bringing automation to a new level—and enabling even the untrained technician to become a test expert in no time.

The iOLM integrates all our expertise into a simple, easy-to-use software that will take your OTDR testing capabilities further than they’ve ever been. And since EXFO designs and optimizes each OTDR model so that it offers the best possible performance for its specific application, your solution will fit to your reality.

iOLM—What Is It and How Does It Work?

The iOLM is an innovative OTDR-based application that uses multipulse acquisitions and advanced algorithms to deliver detailed information on every element on the link.

  • Offers one-touch, automatic analysis and clear link view display
  • Minimizes training and avoids misconfiguration thanks to automatic parameter settings and clear go/no-go results
  • Turns complex OTDR information into simple and accurate analysis with Link-Aware technology, minimizing truck rolls
  • Identifies each event on the network and obtain a straightforward fiber link status with the Optical Link View
  • Provides prompt diagnosis to fix network issues quickly and efficiently
  • Generates OTDR trace files (.sor)
