Overview
The Jonard Tools VFL-300 is a professional-grade visual fault locator kit designed for field fiber optic maintenance and installation. This diagnostic tool is specifically engineered to locate fiber breakpoints, leaks, stress points, and poor connections in both single-mode and multi-mode fiber networks. Its ability to operate effectively within OTDR dead zones makes it an essential instrument for technicians verifying fiber continuity or identifying specific fault locations up to 5 km (3.1 miles) away.
Built for demanding field environments, the unit features a rugged aluminum housing and a compact pen-style design. The device is powered by two included AA batteries and offers up to 60 hours of continuous operation. To prevent accidental battery drain and damage, it includes a rotating protection sleeve that secures the power and mode switch button when not in use.
