AFL Introduces Compact, Long-range Visual Fault Identifier
Westford, MA and Spartanburg, SC – AFL, a manufacturer of fiber optic cable, accessories and equipment, is launching the VFI4 Visual Fault Locator, an essential troubleshooting tool for fiber installation and maintenance technicians. This compact unit injects a high-powered red laser light that provides exceptional brightness and range for locating defects in single-mode and multimode fibers.

AFL VFI4 Visual Fault Identifier

“As with all of our tools, the VFI4 is designed for real-world field testing,” explained Arun Jain, director of product marketing for AFL. “The VFI4 is small enough to fit on a keychain, yet has enough power to reach up to 10 km. It’s a must-have tool for any technician working on fiber-optic networks.”
The light generated by the VFI4’s eye-safe Class 3R laser “leaks out” from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors, enabling technicians to quickly spot faults. Uses include quick continuity checks, fiber tracing, splice verification and Pass/Fail validation for mechanical connectors.
AFL designs a host of test and inspection equipment that are easy-to-use and provide quick results, including OTDRs, fiber identification tools, optical power meters, test kits, cleaning and more. For additional information about AFL, its products and service, visit
