INFAST Fiber Visual Fault Locator 10mW With FC/LC Adapter Kit, VFL 10KM Include Single Mode 9/125um FC Male to LC Female Connector, Red Light Pen for CATV Telecommunications Engineering Maintenance

Visual fault locator can easily and accurately detect all kinds of optical fiber faults, such as fracture, bad connection, bending, opening, etc. The detector emits a 650nm red light for optical fiber tracking. Optical fiber rupture or fault will refract light and produce a bright glow around the fault area. So you can easily find and fix bugs.
The VFL + FC/LC connector kit includes an FC interface to LC interface adapters. 2.5mm universal connector - Detector connectors are compatible with round and square ST, SC, MU, FC, and LC interference of different optical cables.
The 10mW VFL has a strong red light output and can travel up to 10km through optical fibers. Efficient power circuits ensure stable power supply
Small volume, lightweight, convenient for the field test, with constant output power, low battery power alarm, long battery life, multi-interface adaptation, remote detection, and other functions.
