Visual Fault Locator

The FLS-140 is the easiest way to identify optical fibers from end to end and locate polished connector endfaces. Its red laser shines through most yellow-jacketed optical fibers to help you pinpoint breaks, bends, faulty connectors, splices and other causes of signal loss. It has a reach of up to 5 km. The convenient FLS-140 locates faults visually by creating a bright red glow at the exact location of the fault on singlemode or multimode optical fibers.

  • Bright red laser at 655 nm
  • Pulsed and CW operation
  • 40 hours of operation (typical)
  • Standard AAA alkaline batteries
  • Pocket-size pen-style design
  • 2.5 mm universal connector
