Versatile Network Cable Tester with an LCD display for easy tracking and troubleshooting of network cables, including CAT5 and CAT6. Comprehensive cable testing capabilities with Visual Fault Locator and Cable Tracker to test continuity and identify short circuits, open circuits, and crossover issues in network cables. Integrated PoE function to test power supply modes from PoE switches, helping ensure your network setup is functioning . Optical Power Meter functionality that measures optical power and light attenuation across multiple wavelengths: 850/1300/1310/1490/1550/1625 nm. Use scenario: Onsite verification during office installations to confirm CAT5/CAT6 cabling integrity, use the LCD display to review results, and employ Visual Fault Locator and Cable Tracker to locate faults. Use scenario: PoEenabled device deployment in data rooms or network closets, testing power delivery from PoE switches to ensure devices receive appropriate power. Use scenario: Fiberrelated assessments in mixednetwork environments by measuring optical power and attenuation at the specified wavelengths to validate link budgets.
