Anritsu has launched a tri-wavelength optical time domain reflectometer (OTDR) module for its Network Master Pro MT1000A portable optical tester that provides field engineers and technicians with a comprehensive test tool to verify fibre lines in core, metro and mobile networks. The Network Master Pro MT1000A provides a variety of testing capabilities in a rugged and field portable package. It simplifies the task of collecting and interpreting data with a user-friendly graphic interface and clear summaries, allowing users of any skill level to operate the instrument to its full potential. The new module for the Network Master Pro would support a high dynamic range at all wavelengths, including 1,625 nm, which would allow the MT1000A tester to conduct extra-sensitive tests for high-bandwidth networks. Further, supporting high dynamic range  would allow the tester to achieve highly accurate macrobend detection in all single-mode fibre applications. By installing the MU100022A-022 tri-wavelength OTDR module, the Network Master Pro MT1000A can achieve a dynamic range of 46 dB at 1,310 nm and 1,550 nm, and 44 dB at 1,625 nm.

In addition, the new OTDR module features Anritsu’s Fibre Visualiser, which is a fault location function that simplifies the entire testing process. It automatically selects the testing parameters to ensure the proper set up of fibre and provides a graphical summary of the fibre under test in seconds. It also allows individualised PASS/FAIL analysis to simplify fibre optic testing.

According to the company, all Network Master Pro MT1000A OTDR modules will benefit from the new and specialised functions, which will make field testing more efficient. The construction OTDR mode would provide an automated method of testing numerous fibres at multiple wavelengths during cable installation. Moreover, a single set-up screen would initiate a testing wizard and ensure that all fibres are tested and results are stored using consistent file names. Moreover, a bidirectional measurement function has been added for accurate and simple event loss analysis.
