Fluke Networks DSP-4300 Digital Cable Analyzer

It exceeds the Cat 5, Cat 5e, and Cat 6 specifications, achieving Level III accuracy. It also features automatic diagnosing of cable faults, and tells you exactly where the fault is in meters or feet. It is comparable in performance to most desktop models, with the added benefit of being handheld.


With its large on-board memory, you can store a full day's results inside, or detach the multimedia card and plug it into your PC. Featuring Fluke Corporation's LinkWare Cable Test Management software, you can easily review and analyze results for both fiber and copper. Software allows you to edit, view, print, and archive your data. You can then export the data to a PDF.


With the DSP-4300, you can monitor traffic through your Ethernet. Regardless on whether you're using 10BASE-T or 100BASE-TX, you can detect and measure impulse noise better than any other tester on the market. You can also identify hub port connections and tell what standard is met by the respective connections.


The DSP-4000 Series can boost your bottom line by providing fast, accurate testing of high-performance Cat 5e, Cat 6 and fiber optic cabling. Equipped with an exclusive digital platform, this series of testers ensures repeatable accuracy, no matter how many times you retest a link. With high-bandwidth test capabilities to 350 MHz, superior diagnostics and extensive reporting, the DSP-4000 Series provides you with a complete solution for testing, certifying and documenting copper and fiber. And like all Fluke Networks instruments, they're built rugged to withstand the drops and other mishaps that occur in today's network installation environments. The DSP-4300 is the most comprehensive cable testing and certification solution for high-speed copper and fiber networks available.

DSP FTA-420 Fiber Adapters

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.
