The Visual Fault Finder is a visible laser light source used to check continuity, locate breaks, poor mechanical splices and damaged connectors in fiber optic cabling.

Used to verify continuity, test and find breaks in fiber links, locate pinched fiber strands in termination cabinets, or anywhere fiber optic cables are terminated and subject to mechanical damage.

The VFF5 is also an excellent aide to technicians terminating mechanical splices or pre-polished connectors where leaking light is an indicator of a poor fiber cleave or other misalignment.

A hand-held, battery-powered tool, the VFF5 projects a highly visible red light into a fiber optic cable. The VFF5 is used to check continuity of cabling between termination points and to locate bends or breaks in fibers at splicing and termination points.

The VFF5 is useful over a distance of approximately 5km (3.1mi) into multi-mode fiber and single mode fiber. Use it as a stand-alone first-line basic troubleshooting tool, or in conjunction with an OTDR to pinpoint faults. Any breaks will be seen as a conspicuously glowing or blinking red light area (in 3mm or smaller cables).

The VFF5 is equipped with a high-power, day light visible 650nm laser diode which operates either in continuous or flashing mode. The design prevents battery drain due to accidental activation of the tool while inside a tool pouch.

Two AA batteries provide over 30 hours of operation in continuous mode and 80 hours of operation in flashing mode.

The unit is packaged in a pocket-sized, rugged metal housing and is fitted with 2.5 mm universal connector that accepts ST, SC and FC optical connectors.
