Exfo CableSHARK P3 – VF/DSL cable qualifier

The EXFO CableSHARK P3 is a versatile handheld cable qualifier designed for field technicians working with both voice-frequency (VF) and digital subscriber line (DSL) copper networks. This rugged, portable unit combines multiple testing capabilities in a single device, including traditional metallic line testing and advanced DSL qualification. The P3 performs comprehensive cable tests such as DC voltage measurement, resistance checks, capacitance testing, and TDR-based fault location with 1-meter resolution. For DSL qualification, it measures critical parameters including loop loss, noise margin, and attainable data rate. The device features a high-contrast color display with intuitive navigation that simplifies operation for technicians of all experience levels. Its automated test sequences guide users through common testing scenarios, while manual modes allow for customized investigations. The CableSHARK P3 includes a built-in tone generator and probe for cable identification, as well as a digital multimeter for basic electrical measurements. With its long battery life and IP54-rated enclosure, the P3 is designed for demanding field conditions. The unit stores hundreds of test results with timestamps and location data, which can be exported via USB or wireless connection for integration with asset management systems. This all-in-one solution is particularly valuable for technicians maintaining hybrid networks that support both POTS and DSL services on the same copper infrastructure.
