SML-DSL Multifunction Cable Tracer
Multifunction field tracer with network-cable tracing and mapping, PoE checks, and 0.1 m-resolution TDR length testing.
Product Overview
The SML-DSL adds TDR length testing to network-cable tracing, remote wire mapping, and PoE checks. It reports twisted-pair length by pair for structured-cabling acceptance and fault diagnosis. The unit also traces telephone lines, two-core wires, and BNC coaxial cable, while the receiver’s color display consolidates wire map, length, signal strength, and test status.
The product image shows the general series appearance. The panel and interfaces vary by model; refer to the corresponding unit.
Typical Applications
- Locating target network cables at patch panels, switch ports, and wiring closets
- Diagnosing wire order, continuity, open, short, and crossover faults
- Checking PoE port voltage and power type
- Measuring network-cable and pair length
- Tracing telephone lines, two-core wires, and coaxial cable
Use and Safety Limits
Connect a PoE cable only to the dedicated PoE test port; the maximum permitted test voltage is 60 V. For length testing, the cable must be de-energized and its far end left open. The coaxial port is for tracing only, not length or continuity testing. This model does not support tracing 220 V in-wall or underground cables. Never connect it to mains power or an unknown high-voltage circuit.
Features
- Integrated cable tracing and 2-to-8-conductor remote wire mapping
- Measures PoE output voltage and identifies standard or non-standard power
- TDR length testing with 0.1 m resolution and a 500 m maximum range
- Traces telephone lines, two-core wires, and BNC coaxial cable
- 2.4-inch color receiver display with Chinese and English interfaces
