Visual Fault Locator (VFL) is a compact handheld device used in fiber optic technology to locate breaks, bends, and other faults in optical fibers. It emits a visible laser light that can be easily seen by technicians, allowing them to visually trace the fiber and identify points of signal loss or interruption. The VFL is a valuable tool for fiber optic network maintenance and troubleshooting, as it provides a quick and convenient way to locate and pinpoint fiber faults. It is commonly used in FTTH networks to ensure efficient and reliable transmission of data, voice, and video services by identifying and resolving issues in the fiber infrastructure.
