Cable tester Alantec NI056 – network and coaxial tester with TDR, PING and PoE measurement

Alantec NI056 is a compact professional cable tester designed for diagnosing both Ethernet network and coaxial cabling. Equipped with time-domain reflectometry (TDR), PING functionality and PoE measurement, this tester allows installers and technicians to verify continuity, locate faults and check power-over-Ethernet presence during installation and maintenance. The unit supports common cable types used in structured cabling systems and provides numerical and graphical indicators to speed up fault finding and network diagnostics.

Advantages

The device combines TDR-based distance-to-fault measurement with standard cable continuity checks and PING network testing in a single handheld tool, reducing the need to carry multiple instruments. PoE measurement capability identifies presence and basic power characteristics of PoE supplies without requiring separate power meters. A clear user interface and robust build make the tester suitable for fieldwork, while its compact size simplifies transport and on-site use.

Suitable for

• Installation and verification of Ethernet structured cabling (Cat5e/Cat6 and similar)
• Troubleshooting coaxial cable runs in CCTV and RF distribution systems
• Locating cable faults such as opens, shorts and impedance mismatches
• Verifying network device reachability and basic connectivity with PING
• Checking presence of PoE and ensuring PoE-powered devices receive power

Key specifications

• Cable types supported: twisted-pair Ethernet and coaxial
• TDR function for distance-to-fault measurement and fault location
• Integrated PING test for network reachability and latency check
• PoE detection and basic power measurement for PoE verification
• Continuity and pair mapping for Ethernet cable verification
• Handheld form factor with battery-powered operation suitable for field use

How to use

Connect the tester to the cable under test using the appropriate port for Ethernet or coaxial connections. For continuity and pair mapping, select the corresponding test mode and observe the displayed results to confirm wiring and detect opens or shorts. Use the TDR mode to send pulses down the cable and read the displayed distance-to-fault value to locate impedance discontinuities. For network diagnostics, use the PING function to verify device reachability and measure response times. To detect PoE, connect the tester to the Ethernet line and enable PoE measurement to confirm the presence of power and obtain basic parameters.

Usage recommendations

When performing TDR measurements, ensure the cable is disconnected from active equipment to avoid inaccurate readings and potential damage. Use appropriate adapters and cable connections for coaxial and Ethernet interfaces, and follow safe handling procedures when testing live PoE circuits. Regularly check battery status before field work to ensure uninterrupted operation.
