Overview
The VIAVI FFL-050 is a precision visual fault locator (VFL) designed to identify physical layer issues in fiber optic networks. It utilizes a high-intensity 650-nm red laser to pinpoint sharp bends, breaks, and damaged sections of fiber, enabling technicians to quickly troubleshoot and restore connectivity. The device is housed in a compact, ergonomic chassis suited for field operations.
Engineered for versatility, this VFL supports both single-mode and multimode fiber testing. It features a universal 2.5mm connector interface, making it compatible with common industry connectors such as ST, SC, and FC. The tool supports both continuous and flashing illumination modes for distinct fiber identification in high-density patches or complex network environments.
