Visual Fault Locator UP310

This essential tool is a visible red laser designed to inject visible light into a fiber. Sharp bends, breaks, faulty connectors and other faults will “leak” red light allowing technicians to visually spot the defects.
The device is ideal for locating a large number of defects, that occur at connection points in and around fiber cabinets which are hidden in an OTDRs “blind-spot” or dead-zone.
