Synergy 21 S215491V2 Visual Fault Locator (VFL) with Laser Light, 10mW, 650nm, for SM/MM Fibers, 1.25/2.5mm Ferrules, up to 10km, Tester

The Synergy 21 S215491V2 Visual Fault Locator (VFL) is a professional-grade fiber optic tester designed for quick and accurate fault detection in single-mode and multi-mode fibers. With a powerful 10mW laser at 650nm, it can locate breaks, bends, and faults up to 10km on single-mode fibers. The universal 2.5mm connector interface supports SC, FC, and ST connectors, and an included 1.25mm adapter allows use with LC and MU connectors. Powered by two AA batteries, it offers continuous wave (CW) and 2Hz pulsed output modes, making it ideal for field technicians and network installers.

Advantages

High-power 10mW laser ensures visibility over long distances, even in bright environments. The compact aluminum alloy housing is durable and lightweight, perfect for on-the-go use. Dual output modes (CW and pulsed) help differentiate your signal from ambient light. The included 1.25mm ferrule adapter adds versatility for different connector types.

Suitable for

• Fiber optic network installation and maintenance
• Identifying breaks, bends, and poor splices in fiber cables
• Continuity checking and end-to-end fiber identification
