The AQ7275 is one of the best selling OTDRs in the world. Model lineup has been expanded to a total of 9 models to choose from with a dynamic range of up to 45dB . Wavelength capability spans from 850nm (MMF) to 1650nm (SMF). An impressive 0.8m event dead zone makes this model an excellent choice for FTTH and metro, core networks.
Enhancements include a PON option allowing accurate event analysis after a 1x32 splitter with significantly reduced undershoot effects. Also unique to the industry is a built-in section of launch fiber to eliminate the need for a separate launch box.
Latest standard features includes the convenient capability to display a fiber connector inspection probe using one of the unit's standard USB I/O ports.
