A fiber tracking system was constructed at UCLA, consisting of four layers of scintillating fiber ribbons coupled to Visible Light Photon Counters (VLPC's), and was tested by measuring Cosmic-Ray tracks. The total length of the fiber array is 7 meters, 4 meters of scintillating fiber and 3 meters of clear optical fiber, 0.83 mm diameter. An average number of 6 photoelectrons were detected by the VLPC's, 7 meters from the Cosmic-ray interaction point at the end of the fibers. The details of the experimental arrangement and the test results are presented.
