The ST-158007 VDV II Cable Verifier with TDR Meter is an advanced cable tester designed to verify the integrity of copper cables used in voice, data, and video installations. Featuring state-of-the-art wire mapping and Time Domain Reflectometry (TDR), it provides instant fault detection, cable length measurement, and service identification (including ISDN, PBX, and PoE). With support for RJ-11, RJ-12, RJ-45, and coax connections, this versatile tool is essential for professional cable troubleshooting.

Technical Specifications:

What is Time Domain Reflectometry (TDR)? TDR is a technique used to locate faults and measure the length of cables by sending an electrical pulse down the cable and analyzing the reflected signals. The time it takes for the pulse to return indicates the distance to a fault or the end of the cable. Knowing your cable capacitance is crucial in TDR because it affects the propagation speed of the signal. Knowing the capacitance allows you to accurately calculate the distance, as different cables have varying capacitance, impacting the speed at which signals travel.

The ST-158007 VDV II Cable Verifier offers a range of key capabilities, including:

1. Copper Cable Testing: Supports common copper cables used in voice, data, and video installations, including RJ-11, RJ-45, and Coaxial connectors.
2. Wire Mapping: Detects miswires, split pairs, shorts, and opens, ensuring the integrity of cabling systems.
3. TDR Measurement: Provides accurate distance-to-fault measurements with Time Domain Reflectometry (TDR), aiding in troubleshooting.
4. Service Detection: Identifies services such as ISDN, PBX, and PoE on the connected cables.
5. Voltage Protection: Safeguards the device and cable system against voltage overloads of up to 60V.

These features make the ST-158007 a versatile tool for professional cable verification, helping with installation and maintenance tasks across various industries.
