Visual Fault Locator, 10mW Fiber Optic Cable Tester Meter VFL Fiber Optic Tester Kit - Include Single Mode 9/125um FC Male to LC Female Adapter

【Excellent Functions】This fiber optic tester is perfect for field tests because of its multiple functions such as constant output power, multi-interface adaptation, low battery warning, long battery life, and long-distance detection. Use two convenient AA batteries（Not included） 【Long Output Distance】These fiber optic tools have strong output, up to 10-15 kilometers. The high-efficiency power supply circuit ensures a stable power supply. 【Widely Used】2.5mm Universal Connector - the connector of this fiber tester is compatibly designed for ST, SC, FC, LC interferes both in the circle and square shape of different fiber optic cables. It can be used for CATV telecommunications engineering maintenance, integrated wiring system optical fiber engineering, optical device production and research, optical telecommunications, optical measurement drive engineering, etc. 【High Efficiency Visual Fault Locator】Easy identification of fiber breakpoints, poor connections, bending or cracking. Excellent for finding the right fiber to splice or quickly finding a break. Our VFL fiber optic is used for fiber tracing, fiber routing and continuity checking efficiently. It will create a bright glow around a break or fault barrier area in the fiber. 【Crash-proof and Dust-proof Design】Our visual fault locator fiber optic is designed with stainless steel head and aluminum body to prevent crash and dust, and the case ground design prevents damage efficiently.
