The Plug&Play red light source (VFL) easily identifies breaks and bends in the fiber, faulty connectors and splices, and other causes of signal attenuation. The optical power meter (GeX) is designed for high levels up to 27 dBm, which is essential for testing hybrid fiber-coaxial cable (HFC) networks and other high-level signals. In conjunction with a light source that supports automatic wavelength selection/automatic switching, the power meter automatically selects the same wavelength, preventing incorrect measurements.
