FlexScan FS200 OTDR from AFL

High-performance fibre networking testing

The FlexScan FS200 OTDR from AFL offers high-performance fibre networking testing from a pocket-sized OTDR that is user-friendly. It enables both novice and expert field technicians to quickly and reliably troubleshoot Passive Optical Networks (PON) and point-to-point optical networks, or fully characterise newly installed or repaired networks.

Thanks to the FlexScan FS200 OTDR’s innovative SmartAuto Mode, mulit-pulse and multi-wavelength features the OTDR can quickly and accurately scan, detect, identify and measure network components and faults. Testing can be conducted using industry-standard or user-defined pass/fail criteria, with the characterised network displayed using the FlexScan’s intuitive, icon-based LinkMap view.

The FS200 OTDR automates test setup, shortens test time and simplifies result interpretation, which improves efficiency and reduces test costs. The result data can then be stored internally or external, with internal data accessible via USB, Bluetooth or WiFi.

With optional connector inspection, integrated source, power meter and Visual Fault Locator (VFL), the FlexScan FS200 provides an all-in-one solution, that ensures field technicians have everything needed to locate and resolve fibre optic network issues. Uploaded results may be viewed and reports may be gathered using the included Windows® compatible TRM® Test Results Manager software.

FlexScan FS200 OTDR offers:

  • SmartAuto provides network-optimised test settings – In SmartAuto mode, the FlexScan FS200 OTDR automatically determines the characteristics of the network under test and rapidly completes multiple scans using a variety of network-optimised acquisition settings.
  • LinkMap simplifies network troubleshooting – LinkMap with Pass/Fail enables even novice users to easily and accurately troubleshoot optical networks. LinkMap presents an icon-based view of the tested network clearly identifying fibre start, end, connectors, splices, PON splitters, and macro-bends.
  • Bluetooth and WiFi for faster connectivity – Pair FlexScan with AFL’s FOCIS Flex connector inspection probe for fast, easy connector end-face inspection.
  • Multi-Functionality ensures complete testing accuracy – FlexScan FS200 OTDR integrates a Visual Fault Locator (VFL) plus an optional optical laser source (OLS) and optical power meter (OPM) supporting AFL’s unique Wave ID capability. With Wave ID, the power meter automatically synchronises to a single or multi-wavelength Wave ID optical signal sent by an AFL light source. The power meter automatically identifies received wavelengths and measures power and loss at each wavelength, saving significant test time and eliminating setup errors.
