UGREEN Network Cable Tester (LY) – NW167

The UGREEN NW167 actively helps you detect common wiring faults in network and telephone cables, allowing you to prevent connectivity issues before they occur. IT technicians, installers, and even home users rely on it regularly for working with LAN and phone lines.

Features

• RJ45 (8P8C) — Standard Ethernet cables (Cat5, Cat5e, Cat6).

• RJ11 (6P4C / 6P2C) — Telephone cables.

• RJ12 (6P6C) — (Supported on some versions for broader phone line testing).

What It Tests

The NW167 checks for the most common wiring issues that affect connectivity:

• Continuity — Confirms each wire is connected end‑to‑end.

• Open circuits — Detects breaks where continuity is lost.

• Short circuits — Finds crossed or bridged wires.

• Miswiring / Crossed pairs — Identifies incorrect pin order or twisted pairs.

• Split pairs — Alerts to wiring pairs that are incorrectly matched.

How It Works

• LED Indicators: A row of LED lights shows each wire’s status as the tester scans the cable. If all lights light up in correct sequence, the cable is properly wired. Any deviation highlights a wiring fault.

• Automatic Scan: Many models start testing automatically once the cable is connected.

Power and Operation

• Power Source: Uses a standard 9 V battery (not typically included).

• Portable and Lightweight: Compact design fitting easily in toolkits — great for fieldwork or on‑site troubleshooting.

• LED Display: Bright LEDs make reading results easy even in dim working conditions.
