The VOLT uses a visible laser that can measure fiber links of up to 1.5 kilometers, and is accurate to within +-2.5 meters. In addition to length testing, the VOLT's high-intensity laser permits it to do double duty as a visual fault locater, and a pulsing mode allows for easy visual fiber identification. Each unit comes with a protective rubber boot, carrying strap, 9-Volt battery, NIST-traceable certificate of calibration, and CD-ROM with operations manual. The VOLT is designed to measure the length of opticalfiber links up to 1.5km, and is accurate to ±2.5 meters!The VOLT uses a "round-robin" method of measuringfiber length. This is accomplished by looping back twofibers at one end of the fiber run. The round trip timethat the light takes to travel through the fibers isconverted to length in kilometers, then divided by twoto show the length of the fiber cable. There is no needto measure the length of all the fibers; the lengthmeasurement can be applied to all fibers in the cable.The VOLT can also be used to verify the amount of fiberon a spool prior to installation simply by connecting tothe ends of the spool and multiplying the displayedfiber length by two. The VOLT can also be used as a troubleshooting tool to determine if there are breaks, micro-bends, or anyother anomalies causing excessive loss within the first few feet of the fiber under test located in the splicetray. The laser diode in the VOLT injects high-intensity red laser light into the near-end connector. If this lightencounters any anomalies, such as a break or a micro-bend, the light is deflected into the fiber jacket,producing a red glow at the point of the anomaly. Some optical fiber jackets are colored so that it is difficult tosee red light shining through, so it is recommended to keep the room light at a minimum when using the VOLT for visual fault location.
