The VOLT (Visual Optical Length Tester) is a low-cost alternative for users who need to measure the length of optical fibers. Fiber installations are increasingly required to have fiber length measurements to comply with bid requirements. Rather than purchase expensive certification test sets, the VOLT can be added to an installer’s existing fiber test kit for a fraction of the cost. Optical length testers save time by eliminating the need to measure fiber by the cable jacket. Fiber links may also go through multiple cross-connects or have splices in the middle, thereby making jacket markings invalid. Optical measurement of fiber produces accurate results without the need for jacket markings. Optical measurement also saves time by eliminating the need to estimate the length of the fiber run with a measuring wheel. This method is especially troublesome and inaccurate in networks that traverse walls, are in a star topology, or contain riser cables. The VOLT uses a "round-robin" method of measuring fiber length. This is accomplished by looping back two fibers at one end of the fiber run. The round trip time that the light takes to travel through the fibers is converted to length in kilometers, then divided by two to show the length of the fiber cable. There is no need to measure the length of all the fibers; the length measurement can be applied to all fibers in the cable.
The VOLT also functions as a visual fault locator up to 5 Kilometers and measures length of multimode or singlemode fiber loops up to 1.5 Kilometers!
