The MW9060A Optical Time Domain Reflectometer (OTDR) lets you automatically or manually detect fault locations in fiber-optic cables and measure cable splice loss, optical-connector connecting loss, etc. with high accuracy. With its wide dynamic range of 34 dB in wavelength 1.3 µm band or 32 dB in 1.55 µm band, it can make precise measurements with a 10 cm read-out resolution even for a 250 km long-distance measurement. The MW9060A is equipped with a high-speed printer and floppy disk drive so that the waveform can be printed out and saved to microfloppy disk at the site and the data can be processed with a personal computer.
