Jonard Tools TDR-100 Data/Network Cable Tester and TDR
Designed for network engineers, IT professionals, and structured cabling technicians, the Jonard Tools TDR-100 is a versatile diagnostic instrument used to troubleshoot and maintain modern network infrastructure. This comprehensive testing solution integrates Time Domain Reflectometry (TDR) technology, advanced wire pair mapping, and tone tracing capabilities into a single, robust diagnostic unit. It is engineered to rapidly identify breakpoints, measure cable length, test specific wire pairs, and accurately trace active or inactive cables through dense network environments.
Key Diagnostic Features
- TDR Distance Measurement: Utilizes Time Domain Reflectometry to measure physical cable lengths and detect precise breakpoint distances ranging from 6.6 ft to 1,312 ft (2 m to 400 m).
- Comprehensive Wire Mapping: Analyzes structured cabling interfaces to detect line sequences, opens, shorts, wrong pairs, and reverse connections.
- Tone & Trace Capabilities: Includes an integrated tone generator on the main unit and a dedicated receiver probe to trace specific cables in crowded patch panels and bundles.
- Display Interface: Equipped with a clear, full-color 2.5" LCD screen for rapid, intuitive reading of complex test results.
- Probe Flashlight: The tracing probe features a built-in flashlight, facilitating safe and efficient work in dark wiring closets or dimly lit drop ceilings.
- Operating Environment: Rated for use in temperatures from 32°F to 104°F (0°C to 40°C).
