The VIAVI FFL-050 Visual Fault Locator is a compact pocket-sized fibre optic troubleshooting tool designed for rapid identification of fibre breaks, sharp bends, damaged connectors, and continuity faults within optical fibre networks. Engineered for portable field operation, the FFL-050 provides a lightweight and ergonomic solution for fibre tracing and fault location across both singlemode and multimode fibre systems.
Using a visible 650 nm red laser source with 1 mW output power, the FFL-050 enables technicians to visually identify fibre faults by illuminating damaged or stressed sections of fibre cable. The unit supports both continuous and flashing illumination modes for improved visibility during fibre tracing, cable identification, and maintenance operations.
The pocket-sized design provides excellent portability for installation and maintenance technicians working in telecom, FTTH, enterprise, and datacom environments. The integrated universal 2.5 mm connector interface supports SC, ST, and FC connectors, while an optional 1.25 mm adapter enables compatibility with LC and MU fibre connectors.
