Versatile Network Cable Tester with an LCD display for easy onsite monitoring 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 devices are powered correctly and reliably. Optical Power Meter functionality measures optical power and light attenuation across wavelengths 850/1300/1310/1490/1550/1625 nm. Use scenarios Network installation and verification: Deploying a office network or upgrading cabling (CAT5/CAT6) and using the tester to verify continuity, locate faults, and confirm absence of shorts, opens, or crossover problems. PoE device diagnostics: Troubleshooting PoEenabled devices such as IP cameras, phones, or access points by testing PoE power delivery from switches and confirming proper power levels. Fiber and optical assessment: Evaluating optical links or components by measuring power and attenuation across common wavelengths to ensure link integrity and performance.
