Fiber test applications

  • A complete update to the look, feel, operation and performance of our fiber optics applications. The user experience has been redesigned to improve the usability by reducing complexity and adopting modern smart device gestures/techniques for increased control to get techs of any skill level up-and-running in no time while reducing test and reporting times
    • Free update for all SmartOTDR, T-BERD/MTS-2000 V2 (S/N starting with EBAKxxx), T-BERD/MTS-4000 V2 (S/N starting with EBAHxxx), T-BERD/MTS-5800 (model numbers 5811P, 5822P, 5882, 5800-100G)

True bi-directional fiber certification solutions to improve fiber technician efficiency, driving operational excellence with FiberComplete PRO (formerly TestPRO)

TrueBIDIR software option adds real time on-board bi-directional OTDR result analysis (patented)

  • Immediate result allows you to perform corrective actions while you are still on site, reducing future site revisits
  • Improves event location and measurement accuracy
  • Provides greater detail by finding events hidden by uni-directional OTDR testing
  • Gives ‘true’ event loss to immediately assess ‘gainers’ and false negative events
  • No additional post processing effort required

Data exchange via instrument test port and fiber under test (patent pending)

  • Synchronize instruments to eliminate test configuration errors and reduce instrument setup time
  • Eliminate file transfer time and effort with automatic retrieval of test results from remote/far-end instrument
  • No additional communications media required (WiFi connection, Smartphone tethering, USB, etc.)

Avoid site revisits and retests which lead to poor KPI with auto file naming and storage to guarantee correct results pairing for valid bi-directional analysis

Reduce post processing effort with on-board (.pdf) report generation

Remove time, complexity and cost when certifying multi-fiber (MPO) cables, automatic sequence of 12 x FiberComplete (IL, ORL & OTDR) measurements including auto-detection of cable polarity type and cable mapping.

Try the bi-directional OTDR results analysis for 45 days for free
Requires 4100 A, B, or C module hardware to be installed on a 2000 or 4000 V2 platform

  • Connect you instrument to a WiFi or Ethernet network
  • Update your T-BERD/MTS-2000 or 4000 V2 mainframe to this latest 21.50 version
  • On your instrument press ‘Home –> add options –> install from server’ the trial license options are shown on the left of the screen
  • Ensure only the ‘FCOMP PRO feature for OTDRs’ and ‘True Bidir FCOMP-PRO OTDR measurement’ options are checked/selected
