| The MW9070B is a high-performance mini-OTDR for installation and maintenance of subscriber fiber optic lines and other fiber optic cables. It automatically detects the positions of faults in the cable and displays an event table listing faults and a trace waveform. Despite the large 7" screen, the high-performance mini-OTDR is just the size of a B5 file folder and weighing in at only 3.2 kg. The MW9070B is designed with a wide dynamic range and short dead zone and is indispensable for detecting faults in optical trunk lines, subscriber lines, optical CATV cables, optical LANs, and other types of fiber optic cables. In addition, it is also invaluable in measuring transmission line losses, connection losses, return loss, and other parameters. Six optical units are available, depending on the wavelength and type of optical fiber, making the MW9070B an economic choice for a wide range of applications.
