Description
Overview
GAOTek visual fault locators are an intelligent meter of a new generation for the detection of fiber communications systems. With the popularization of optical network construction in cities and countryside’s, the measurement of optical network becomes short and dispersed; it’s specially designed for that kind of application, economically, and having outstanding performance.
