A hand-held, battery tool, the VFF 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 VFF is equipped with a high output, extra long-life, 650nm laser diode which operates either in continuous (CW) or Modulated (MOD; 1Hz pulse) mode. A pushbutton allows the user to select the mode while preventing accidental operation. Any breaks will be seen as a conspicuously glowing or blinking red light area (in 3mm or smaller cables). A red LED on the outer case echoes the operation mode selected. The VFF is useful over a distance of approximately 5km (3.1mi) into multimode fiber and single mode fiber and can be used with single channel 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 2.5 mm universal connector that accepts ST, SC and FC optical connectors. The VFF is also an excellent aide to technicians terminating mechanical splices or internal splice style connectors where leaking light is an indicator of a poor fiber cleave or other misalignment. Advanced fiber optic testing and troubleshooting capabilities are available with the FIBERTEK™ modules for the LANTEK® 6/7G as well as the LANTEK® II series cable certifiers. FIBERTEK™ certifies fiber installations by measuring the attenuation and length of a pair of fibers simultaneously and generating printed certification reports.
