30mW 30KM Visual Fault Locator(VFL) Red Light Pen Fiber Optic Cable Tester Testing Equipment, Fiber Checker/Decector/Finder

(2 customer reviews)



  • 1. EASY AND ACCURATE IDENTIFICATION – It can easily and accurately detect and locate fiber breaks, poor connections, bending or cracking. The detector will emit a 650nm bright light for fiber tracing, breaks or faults in the fiber will refract the light;
  • 2. PRACTICAL DESIGN AND EXCELLENT FUNCTION – Small size and lightweight, it is portable and easy for field test with multiple functions such as constant output power, lower battery warning, long battery life and long distance detection;
  • 3. WIDELY USED: The 2.5mm universal connector of the detector is compatibly designed for ST, SC, FC interferes both in circle and square shape of different fiber optic cables.Test for both single-mode and multi-mode cables;
  • 4.LONG OUTPUT DISTANCE: This 30mW visual fault locator with battery output strong red light goes 20-30 kilomters far, high effective power circuits allows for stable power;
  • 5.PORTABLE: Pen-type design with pouch make it portable, easy to check fiber faults with visual fault locator, rugged,Dust-proof design keep fiber connectors clean;
