It's ideal to verify continuity, test and find breaks in LANs, fiber data links and loops, telephone, shipboard and other vessels, and intrinsically safe process applications where fiber is used instead of copper.
A hand-held, battery-powered tool, the VFF5 projects a highly visible red light into a fiber optic cable. The operator simply looks at the length of cable and where light is seen, there is a break. The VFF5 is equipped with a high-power, extra long-life, 670nm laser diode which operates either in Continuous (CW) or Modulated (MOD; 1Hz Pulse) mode. A slide switch allows the user to select the mode. Any breaks will be seen as a conspicuously glowing or blinking red light area. A red LED on the outer case echoes the operation mode selected.
The VFF5 is useful over a distance of 5km (3 miles) and can be used with single-mode and multimode cable. Use it as a stand-alone first-line basic troubleshooting tool, or in conjunction with an OTDR to pinpoint faults. The unit is packaged in a pocket-sized, rugged metal housing and is fitted with a standard ST connector.

Optional universal 1.25mm Adapter (See Part #35531 below) converts the VFF5 for use with LC or MU connectors as well.
