AFL has unveiled the VFI4 Visual Fault Identifier. The instrument measures 3.1 x 1.8 x 0.8 inches yet features an output power of 5.0 mW for a 10-km range. It can be used as a troubleshooting tool for by fiber installation and maintenance technicians on both single-mode and multimode fiber.
The VFI4 uses an eye-safe Class 3R laser whose red laser light leaks from sharp bends and breaks in jacketed or bare fibers as well as poorly mated connectors. This leakage enables technicians to quickly spot faults for continuity checks, fiber tracing, splice verification, and Pass/Fail validation for mechanical connectors. It comes with a pair of adapters. The 2.5-mm universal adapter accepts FC, SC, ST, and similar connectors, while the 1.25-mm universal adapter accepts LC and MU connectors.
“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.”
