VF 610 Visual Fault Locator


The VF 610 is a high output visible laser designed to locate and identify faults in fiber optic cables, jumpers, patch panels, and other cable splice areas. The visual fault locator may be used within the OTDR “dead zone” to identify breaks and faults in the fiber. The VF610 allows for fiber continuity on multimode or singlemode fiber up to distances of 5 km.

This compact instrument includes a 2Hz modulation feature to enhance the identification of problem areas. A 3V CR2 lithium battery providing over 1000 operations provides power to the unit. A rugged 2.5mm universal adapter interface allows the unit to mate to standard 2.5mm ferrules (SC, ST, FC connectors) and an additional accessory modifies the interface to accept 1.25mm ferrules.
