Hobbes Fiber Checker Pro - visual fault locator (VFL)

The Hobbes Fiber Checker Pro is a professional Visual Fault Locator (VFL) designed for quick and accurate fault detection in fiber optic networks. With a 650 nm laser and 1 mW output power, it identifies breaks, bends, and poor connections in single-mode and multi-mode fibers up to 5 km. Its compact aluminum alloy housing and universal 2.5mm ferrule connector make it ideal for field technicians and network installers.

Advantages

High visibility 650 nm laser with continuous wave and 2 Hz modulated modes for easy fault pinpointing. Long battery life of over 50 hours from two AAA alkaline batteries ensures all-day operation. The rugged aluminum alloy housing withstands demanding job sites, while the dust cap protects the connector when not in use.

Suitable for

• Fiber optic network installation and maintenance
• Visual fault location in patch panels, splice trays, and termination points
• Continuity checking and fiber identification
