Description
Overview
GAOTek fiber optic mini smart handheld OTDR for broadband fiber installation is a unique mainly designed for construction and maintenance of telecommunication and CATV networks. It can be widely used in engineering construction, maintenance test and emergency repair of all fiber optics related systems. Comparing with a regular OTDR, it is more compact in size and easier for field use.
