Anritsu MW9060A Optical Time Domain Reflectometer

The Anritsu MW9060A is a portable Optical Time Domain Reflectometer (OTDR) engineered for rapid event profiling and fault location in fiber-optic installations. It enables fast, accurate network commissioning and troubleshooting across single-mode and multimode fibers at distances up to 250 km. The instrument combines high-speed measurement with operational efficiency through procedure and event registration functions that minimize setup time. Built-in data storage via 3.5-inch floppy disk drive and high-speed printer support on-site documentation and reporting, while optional GPIB connectivity enables remote control and automated data transfer.

– Key Features

• Measurement Functions: Fault location detection, splice loss measurement, connector loss measurement, return loss capability
• Waveform Processing: Simultaneous two-waveform display, six-level smoothing for S/N optimization, full-trace display via attenuator switching, relative distance measurement from cursor position
• Efficiency Automation: Procedure function records and executes multi-step measurement sequences with single key activation; event registration function measures pre-registered points and tabulates results
• On-Site Reporting: High-speed built-in printer outputs CRT displays (73.1 × 57.1 mm) in approximately 7 seconds; measurement operations continue during printout
• Data Storage: 3.5-inch FDD (1.44 MB IBM-PC or 720 KB NEC PC-9800 format) stores approximately 700 measurement waveform screens per 2HD diskette in MS-DOS format

– Typical Applications

• Long-haul terrestrial fiber network commissioning and maintenance
• Short-haul metropolitan area network troubleshooting
• High-resolution event analysis in critical installations

– Compatibility & Integration

Plug-in wavelength units (MW0947B, MW0944B) configure the instrument for specific fiber types and measurement requirements. Optional GPIB interface enables external system control and data archival to host computers.
