Tester optical fibers LAN POE OPM VFL Noyafa NF-8508 NOYAFA Noyafa NF-8508 Fiber Optic Meter with Visual Damage Locator, OPM, Cable Detector, Wire Map, Length Measurement, PoE Testing, Flash Port for Quick Steam Finding The most important features: Optical power meter and visual damage locator - Can measure 7 standard wavelengths, 850/1300/1310/1490/1550/1625/1650, test range -70dBm 10dBm, red light source 10mw. Anti-interference receiver - You can quickly and accurately locate the target wire in the wiring harness using receiver anti-interference probes, NCV and adjustable sensitivity. For dark work environments, LED lights are ideal. Detect hidden cables — Adjust the receiver sensitivity to locate cables deep in the ground, ceiling, or wall. LAN cable test - Tests short circuit failures, circuit breaks and LAN intersections. Length test - Measures the length of CAT5/CAT6 cables do 200m, can be measured in meters, yards or feet. PoE test - can test information about standard PoE device, such as PoE voltage, power polarity, power mode, as well as PSE type (af or at standard) Port Flashing - Determine the correct connection port by observing the same flashing rate on the switch/router port do the target cable is connected Data Visualization - The new generation of cable testers and locators has a high-resolution screen that displays all parameters and functions visually. More compact and more powerful than its predecessor QC Test - Tests the crimping quality of crystal heads. Battery life is longer - Set the backlight off time and auto-off time, and charge the built-in lithium battery with a universal Type-C cable. Certification - passes RoHS, FCC and CE compliance tests, and Noyafa is certified ISO 9001.
