Complete solution for testing and certifying high-speed Fiber Networks

Fluke Networks offers the most complete line of Fiber Test Adapters for testing and certifying Single mode, Gigabit and Multimode fiber optic cabling systems.  These Fiber Test Adapters are high-performance, high-productivity fiber test options for the DSP-4000, DSP-4100 and DSP-4300  Digital CableAnalyzers.

Choose the world's first dual-fiber, dual-wavelength Multimode Fiber Test Adapter to expand the capabilities of Fluke's Digital Cable Analyzers. It easily attaches to the Fluke DSP-4300, DSP-4100 and DSP-4000 testers for bi-directional testing of multimode links. Model DSP-FTA420S measures loss and length on multimode fiber links easily and accurately. It uses LED light sources at 850 and 1300 nm. Use this optional high-performance, high-productivity multimode test adapter to document certified test results. In addition, the timesaving FindFiber feature provided by the DSP-FTA420S enables users at both ends to make a quick check for and locate a signal from the other end. Valuable time spent searching for proper end-to-end connections is minimized.


  • Test two fibers and two wavelengths simultaneously, automatically saving the test results.
  • Perform bi-directional testing on both fibers under test and save results for both in one record.
  • Utilize Fluke Networks' CableManager Software for comprehensive results management and report generation.
  • Automatically measure length and propagation delay along with loss.
  • Verify optical connectivity and determine which fibers go to which connectors at a patch panel.
  • Communicate with a person on the other end of the fiber.
  • Track the maximum and minimum power throughput of the test.
  • Withstand drops and other mishaps that occur on the job.
