A Visual Fault Locator (VFL) can help verify this polarity by sending the visible red laser light through the fiber and tracking its patch to the other end of the fiber cable connector. By injecting the light from a visible source, such as a LED, laser or incandescent bulb, one can visually trace the fiber from transmitter to receiver to ensure correct orientation and check continuity besides. The laser-powered VisiFault Visual Fault Locator is a cable continuity tester that locates fibers, verifies cable continuity and polarity.
