Description
Overview
GAOTek telecom line testers have a unique mainly designed for the construction and maintenance of telecommunication and CATV networks. It can be widely used in engineering construction, maintenance tests, and emergency repair of all fiber optics-related systems. Compared with a regular OTDR, it is more compact in size and easier for field use.
