It is widely used in the installation, troubleshooting, modification and maintenance of single-mode and multi-mode fiber-optic cables in metropolitan area networks, wide-area networks, CATV and other communication systems. It is necessary to locate and eliminate faulty connectors and bad connection points in long-distance optical fibers. The DT-620 is an excellent, affordable test tool.
