Yokogawa AQ7275

The Yokogawa 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. Just push one button to switch multiple wavelengths and perform measurement automatically.
Measured waveforms for multiple wavelengths are displayed on a single screen, so it is easy to compare the waveforms. The measured data is saved to memory. The fault event display function detects and displays abnormal connection or reflection points. Of the events detected by this function, abnormal events that cross a specified threshold value are highlighted in the event table and waveform display.
