NOYAFA NF-859GS Network Cable Tester with red Light Pen 10mw Visual Fault Locator,for POE RJ45 RJ11 CAT5 CAT6 Cable Toner Continuity Test/Length Measure Fault Distance/Wire Tracer Ethernet LAN

Features & Benefits

• 8-in-1 Versatile Testing Capabilities: This network tester combines POE testing, cable diagnostics, continuity checks, port flashing, cable length measurement, LED flashlight, and UTP/STP validation into one device. It eliminates the need for multiple tools, streamlining network setup, troubleshooting, and maintenance across various cable types and environments.
  
  
• Cable Length & Fault Distance: With auto-calibration-free length measurement (2.5–200m) and fault detection for opens, shorts, and crossed wires, this tool quickly identifies problems. It reduces downtime and repair costs by pinpointing fault locations with accuracy, speeding up troubleshooting.
  
  
• Adaptive Three-Mode Scanning: Offering Normal, Anti-Interference, and POE modes, the tester ensures reliable results in noisy environments or complex setups. These modes help minimize false readings, providing accurate diagnostics in a variety of network conditions.
  
  
• Port Flash for Rapid Network Port Identification: The Port Flash function triggers an LED light on connected hubs or switches, making it easy to locate corresponding ports. This feature is particularly helpful in dense network racks, saving time during installations or audits.
  
  
• Comprehensive POE Diagnostics: This tester supports POE diagnostics for IEEE 802.3af/at standards, detecting live voltage, PSE types, pin polarity, and crossover methods. It ensures safe and compatible POE device integration, verifying high-power and non-standard setups.
  
  
• Continuous Cable Integrity Testing: It tests RJ45/RJ11 crimps for opens, shorts, and crossovers and supports both STP and UTP cables. This feature ensures properly installed connectors, preventing connectivity issues and ensuring long-term network reliability.
  
  
• Built-in LED Flashlight: The built-in LED flashlight enhances visibility in low-light environments, making it easier to work during field inspections or in dimly lit areas.
