FS300-00-2000 Revision AR 2026-01-08 Specifications are subject to change without notice. Test and Inspection 1 FlexScan ® FS300 Quad and HDR OTDRs AFL's FlexScan FS300 series includes both a combined single-mode/multimode test set and a high dynamic range single-mode test set. Both are feature-rich solutions for detecting, identifying, locating, and resolving optical network issues. Designed for novice and expert technicians alike, these devices excel in diverse environments including data centers, fiber-to-the-home deployments, and long-haul networks. The FlexScan FS300 automates test setup, shortens test time, and simplifies results interpretation, improving efficiency and reducing costs. All-in-one test capability: The FlexScan FS300 product family includes an integrated VFL, broadband and/or PON power meter, and light source. They can be easily paired to AFL’s award-winning FOCIS family of inspection scopes for single-fiber and/or MPO and OptiTip ® multifiber inspection, ensuring technicians have everything they need to locate and resolve optical network issues. Performance-packed: With automated multi-pulse acquisition, up to 45 dB dynamic range and best-in-class dead zones, FlexScan OTDRs test multimode and/or single-mode networks – including FTTH PONs and POLANs up to 1:128 split ratio – while still detecting and measuring events down to <0.8 meters apart. User-friendly: The FS300 enables both expert and novice technicians to quickly and accurately detect, locate, identify and measure optical network components and faults. It applies industry-standard or user-set pass/fail criteria and displays results using traces or LinkMap color-coded icons that immediately show the health of the network. Pocket-sized, easy to use: The FlexScan FS300's compact design features a large, bright 5-inch touchscreen display (800 x 480) that's readable indoors and outdoors without requiring a stylus. With >12-hour battery operation and intuitive icon-driven interface, it's highly transportable and simple to operate. Multiple sharing and reporting options: Results can be stored internally, saved to a USB, and downloaded via USB cable or Bluetooth (via Flex App). Reports can be generated directly from the unit using Print-to-PDF feature, or downloaded results can be reported using the included FlexReports ™ Test Results Manager software. Reports can also be viewed on AFL's FlexApp. Optical Port Saver included: AFL's field-replaceable Optical Port Saver, helps to avoid expensive service repairs to replace connectors damaged due to poor cleaning practices and/or normal wear-and-tear. Features • Multimode and Single-mode OTDR, including PON test • SmartAuto ® test mode 1-button automated testing for fast results • Data Center test mode, for as low as <1 second per fiber OTDR test • Pocket-sized, weighs less than 1 pound, 12-hour battery • LinkMap ® color-coded icons for easy troubleshooting • Integrated Source, Power Meter and VFL • Robust reporting including Print-to-PDF • Includes field-replaceable Optical Port Saver Applications • Point-to-point and PON verification and troubleshooting • Locate faults exceeding industry or user pass/fail thresholds • Fast data center multi-fiber cross connect or interconnect verification and troubleshooting • Long-haul fiber network verification and troubleshooting Be ready for anything with these feature-rich OTDR solutions

FS300-00-2000 Revision AR 2026-01-08 Specifications are subject to change without notice. Test and Inspection 2 FlexScan ® FS300 Quad and HDR OTDRs Dramatically Reduces Test Time In SmartAuto or Data Center test mode, FlexScan OTDRs automatically analyze and test the network using a variety of network-optimized settings to precisely locate, characterize and identify network events with one button push. In the FS300 HDR, Data Center test mode completes tests in as low as <1 second per fiber. Loss and reflectance are measured for connectors, splices, splitters and macro-bends. FlexScan OTDRs even check for live fiber and verify OTDR launch readiness before initiating a test. Simplifies Network Troubleshooting LinkMap ® color-coded icons enable even novice users to easily and accurately troubleshoot optical networks. LinkMap clearly identifies fiber start, end, connectors, splices, PON splitters, and macro-bends. A LinkMap Summary provides end-to-end link length, loss and ORL. Loss and reflectance of detected events are compared to industry-standard or user-defined pass/fail thresholds, and the results are displayed with clear pass/fail indications. Users can instantly toggle between LinkMap and trace views. Multimode and Single-mode plus PON Testing in One OTDR FlexScan Quad OTDRs are the ideal test tool for verifying and/or maintaining both single-mode and multimode networks. Unlike most Quad OTDRs, FS300 OTDRs test both point-to-point networks and FTTH PONs/Passive Optical LANs (POLANs). Connectivity FlexScan OTDRs easily pair with AFL's award-winning FOCIS ® family of connector inspection probes for fast, easy single-fiber and/or multi-fiber connector end-face inspection. Images and pass/fail results can be transferred to the FlexScan for display and/or archiving with OTDR results. FlexScan results can be transferred wirelessly via the free FlexApp to a smart device for real-time reporting using the included Windows-based FlexReports ™ Test Results Manager software. Monitoring test results in real-time can detect errors while the tech is still in the field, preventing future truck rolls. OTDR, OLTS, and VFL Testing with a Single Tool FlexScan optionally includes a Wave ID optical light source (OLS) and optical power meter (OPM). With Wave ID, the OPM auto-synchronizes to a single or multi-wavelength Wave ID optical signal transmitted by an AFL light source. The OPM reports detected wavelengths and measures power and loss at each wavelength, saving significant test time and eliminating setup errors. The integrated Visual Fault Locator’s eye-safe red laser enables users to visually pinpoint the location of macro-bends and fiber breaks often found in splice closures and fiber cabinets.

Versatile Fiber Testing for Any Network
AFL's FlexScan FS300 series includes both a combined single-mode/multimode test set and a high dynamic range single-mode test set. Both are feature-rich solutions for detecting, identifying, locating, and resolving optical network issues. Designed for novice and expert technicians alike, these devices excel in diverse environments including data centers, fiber-to-the-home deployments, and long-haul networks. The FlexScan FS300 automates test setup, shortens test time, and simplifies results interpretation, improving efficiency and reducing costs.
The Competitive Edge
All-in-one test capability: The FlexScan FS300 product family includes an integrated VFL, broadband and/or PON power meter, and light source. They can be easily paired to AFL’s award-winning FOCIS family of inspection scopes for single-fiber and/or MPO and OptiTip® multifiber inspection, ensuring technicians have everything they need to locate and resolve optical network issues.
Performance-packed: With automated multi-pulse acquisition, up to 45 dB dynamic range and best-in-class dead zones, FlexScan OTDRs test multimode and/or single-mode networks – including FTTH PONs and POLANs up to 1:128 split ratio – while still detecting and measuring events down to <0.8 meters apart.
User-friendly: The FS300 enables both expert and novice technicians to quickly and accurately detect, locate, identify and measure optical network components and faults. It applies industry-standard or user-set pass/fail criteria and displays results using traces or LinkMap color-coded
icons that immediately show the health of the network.
Pocket-sized, easy to use: The FlexScan FS300's compact design features a large, bright 5-inch touchscreen display (800 x 480) that's readable indoors and outdoors without requiring a stylus. With >12-hour battery operation and intuitive icon-driven interface, it's highly transportable and simple to operate.
Multiple sharing and reporting options: Results can be stored internally, saved to a USB, and downloaded via USB cable or Bluetooth (via Flex App). Reports can be generated directly from the unit using Print-to-PDF feature, or downloaded results can be reported using the included FlexReports™ Test Results Manager software. Reports can also be viewed on AFL's FlexApp. Field-replaceable
Optical Port Saver included: AFL's field-replaceable Port Saver, helps to avoid expensive service repairs to replace connectors damaged due to poor cleaning practices and/or normal wear-and-tear.
