SML-8168D Smart Network Cable Tester
For wire mapping and RJ45/RJ11 checks within 10 cm of the connector; switch-connected checks require non-PoE or standards-compliant PoE switches.
- Complete wire mapping with the main and remote units
- RJ45/RJ11 single-ended testing covers the near-end area up to 10 cm from the inserted connector
- 1-8 indicators show conductor test results; G is the shield indicator
A switch-free smart network cable tester with wire mapping and RJ45/RJ11 single-ended near-end checks, a built-in lithium battery, and USB Type-C use while charging.
Product Overview
The SML-8168D is a switch-free, USB Type-C rechargeable smart network cable tester. For wire mapping of network, telephone, and shielded network cables, connect the cable ends to the main and remote units. For a single-ended test, connect only the cable under test to the main unit and do not attach the remote. Single-ended testing supports RJ45 network and RJ11 telephone cables, covers the near-end area up to 10 cm from the inserted connector and does not limit the total cable length, but it cannot replace complete wire mapping for wire order and remote continuity.
The built-in 3.7 V / 800 mAh lithium battery charges from a 5 V / 1 A USB Type-C supply in approximately 1 hour and supports use while charging. The red work indicator is on during single-ended testing, and the yellow charging indicator is on while charging. Before the battery is full, the red work and yellow charging indicators may be on at the same time during use while charging; the yellow indicator turns off when charging is complete.

Typical Applications
- Complete wire mapping in structured cabling projects
- Rapid near-end checks on newly terminated RJ45 and RJ11 connectors
- Network, telephone, and shielded cable troubleshooting
- Routine maintenance requiring a rechargeable tester

Use and Safety Limits
For wire mapping, connect the cable ends to the main and remote units. When the far end of the cable remains connected to a switch, single-ended testing is limited to non-PoE or standards-compliant PoE switches; connect only the main unit and do not use the remote. The tester does not identify the switch category or PoE type. If the category cannot be confirmed, treat it as a non-standard PoE switch and disconnect the switch and its power first. A non-standard PoE switch is covered only by the nominal 60 V burnout protection; test functions are unavailable and their results must not be used.
The 60 V value is a nominal protection rating, not a normal operating voltage or PoE-detection capability. Use only an undamaged USB Type-C cable and a 5 V / 1 A power source. The built-in lithium battery must not be disassembled or replaced by the user. Stop testing and charging and disconnect external connections if the tester becomes wet, damaged, unusually hot, or emits an unusual odor. Do not connect it to mains power, high-voltage wiring, or a circuit of unknown voltage.
