Cixi Guangjia Visual Fault Locator Kit 1KM with 2.5mm Universal Connector FC Male to LC Female Adapter, VFL Red Light Pen for Network Cable Test, Fiber Optic Source Tester Detector Meter for FC,SC,ST,LC

【Widely Compatible】The 2.5mm universal connector and included LC adapter make the detector compatible with ST, SC, FC, and LC connectors, and can be used with different circular and square optical cables. 【Effortless Fault Detection】The visual fault locator accurately detects and locates fiber breaks, poor connections, bending or cracking. Emitting a strong 650nm light, faults in the optical fiber refract the light, providing an easy way to locate the problem. 【Long-distance Output】With its powerful output and strong red light, the VFL can detect faults up to 1 kilometers away in fiber optic cables. The efficient power supply circuit ensures stable power output. 【Powerful Functions】This portable and easy-to-use VFL device features constant output power, low battery warning, long battery life, and long-distance detection, making it an essential tool for engineers. 【Practical Design】Compact and lightweight, with a pen-style design and carrying pouch for easy portability. The VFL is designed with a stainless steel head and aluminum body to prevent damage from collisions and dust, and the case grounding design effectively prevents electrostatic discharge damage.
