Upon completion, fiber optic cable application projects will often require the documentation of test results that record the efficiency of the network. If you are troubleshooting a fiber optic network, Bonelinks supplies Visual Fault Locators (VFLs) to diagnose problems quickly.

The Visual Fault Locator is a compact but robust fiber optic testing tool with adjustable output power settings of 5mw, 15mw, 20mw, and 30mw. It serves multiple purposes, such as pinpointing sharp bends and breaks in both jacketed and exposed fiber. Additionally, the fiber optic tester proves handy in identifying connectors within patch panels and differentiating fibers during splicing operations. Combined usage with handheld optical light sources, it offers a quick and accurate cable testing solution.

The fiber tester is essential for any fiber optic network. It can help identify and solve problems quickly, saving time and money. Bonelinks has a wide types of fiber optic testing products to help certify that power losses are within standards and to troubleshoot broken and high loss links on single-mode and multimode fiber all with ease-of-use, accuracy, and durability.


  • Built in over-current protections circuit, even if it is full, there is no need to worry about overload and damage to the machine.
  • Replaceable and rechargeable .
  • Push-type automatic flip, more convenient to work, for easy operation in dark environments.
  • Standard 2.5mm interface.
  • Fine quality probe, the penetration distance is longer and the service is longer.


Common applications include detecting fiber breaks in optical fiber, detecting defective connectors, continuity checks, finding loss inducing bends, and for optimizing fiber splices.
