Optical time-domain reflectometer

16 July 2014 Test & Measurement

The latest addition to AFL’s M-series optical time-domain reflectometer (OTDR) family – the large screened M710-40 – has been given TruEvent advanced analysis as well as optics that provide 44/42 dB of dynamic range at 1310/1550 nm.

This is AFL’s longest-range OTDR and provides the necessary performance for virtually any network testing needs. Applications include Tier 1 and Tier 2 testing and reporting of single-mode and multi-mode networks, test and certification of campus and central office networks, inspection of fibre end-faces and testing of Distributed Antenna System (DAS) fibre infrastructure.

As with the M700 range, the M710 combines event analysis with ease of use in a rugged, handheld package. With a single-mode dynamic range option of 44 dB and several other models, it is ideal for testing and troubleshooting LAN/WAN, metro, FTTx and long-haul networks. Industry leading dead zones of less than 1 metre also improve the user’s ability to locate and measure events.

The OTDRs supports full auto, manual and real-time test modes, multi-wavelength testing and visual inspection using the DFS1 Digital FiberScope. This allows users to view and then document connector end-face images along with their OTDR traces. Pass/fail acceptance to TIA/ISO values or user-defined values can be set to alert the test operator of failing or marginal events, with event tables that can help even novices to work quickly and accurately.

Thousands of test results may be saved as standard .SOR files and stored internally or on the supplied USB drive. Test results are transferable via a USB cable or USB drive to a computer for analysis with Windows compatible Test Results Manager (TRM) software.

OPM loss values for a cable in one or two directions can be displayed in a table on the instrument for evaluation and comparison. Acceptance reports generated using TRM can include loss tables, OTDR traces with summary and event information with pass/fail indication, and channel maps.
