Visual Fault Identifiers
A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects.
The VFI is an ideal tool for locating a large number of defects that occur at connection points in and around fiber cabinets which are hidden in an OTDRs “blind-spot” or dead-zone. AFL offers VFI units for both single-ferrule and multi-ferrule connector styles.

VFI4 injects high-powered red-laser light to provide exceptional brightness and range for locating defects in single-mode and multimode fibers. The light generated by these units will escape from sharp bends and breaks in jacketed or bare fibers, as well as poorly mated connectors enabling technicians to quickly spot faults. The universal connector interface mates with many connector styles without needing an adapter.
Multi-Fiber network construction is time consuming, complicated, and often built by more than one crew with mixed sets of documentation. Mistakes, such as mislabeling, are almost guaranteed. AFL’s Multi-Fiber Identification System (MFIS) provide 100% multi-fiber network continuity assurance. It is a simple user-friendly way to verify network construction quickly, correctly, and efficiently.
