Description

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 1×32 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.

The AQ7275 OTDR condenses the total working time during on-site tests as the time to power up the device, the time taken to make measurements, and the time to analyze and store the measurement results are reduced significantly. The measurement results can easily be transmitted to computers using the USB interface or the Ethernet and the analysis software (optional) helps with preparation of reports on a computer.

The worldwide spread of broadband services has stimulated the installation of optical fiber in metro and access networks, which in turn has increased the demand for portable and reliable test equipment to aid the installation and maintenance of these networks.

  • Automatic Setting of Measurement Conditions – Full Auto Mode

    Simply select the measured wavelength and the AQ7275 takes care of the rest by automatically setting the optimal measurement conditions and by performing measurement and event analysis, and fully automated data saving.
  • Automatic Setting of Measurement Conditions – Wizard Mode

    Display the guidelines for the setup items from the Setup menu. Follow the step-bystep instructions to complete the setup.
  • Automatic Setting of Measurement Conditions – Detail Mode

    This mode allows you to set all the detailed settings, not only the measurement and analysis settings but also the screen display and system settings.
  • Macro’s with Predefined Procedures – One Button Mode

    Simply select previously set measurement procedures and then push a button. You can execute up to 5 previously set and saved measurement procedures automatically. Measurement and analysis conditions can be loaded from a file, making it easy to set up measurement procedures you executed previously.
  • Measurement with Auto Wavelength Switching press a button – Multi-Wavelength Measurement

    Simply select previously set measurement procedures and then push a button. You can execute up to 5 previously set and saved measurement procedures automatically. Measurement and analysis conditions can be loaded from a file, making it easy to set up measurement procedures you executed previously.
  • Plug Check Function–Checking the connection with the OTDR

    Never spoil measurements with poor connections or dirty plugs The plug check function monitors the condition of the OTDR’s optical input/output connectors and displays an alarm if the connection is not properly made. This function is useful for checking for damage, dirt, or other problems with optical plugs at the OTDR or on the fiber under test, and for helping technicians to remember to connect the fiber under test
  • Detecting Abnormal Events –Fault Event Display Function

    The fault event display function detects abnormal connection or reflection points and displays them. Of the events detected by the event detection function, abnormal events that cross a specified threshold value are highlighted in the event table and waveform display.
  • Measurement with Comparison to Reference Waveform –Trace Fix Function

    This function enables you to freeze the display of one waveform and overlap it on real-time or averaged waveforms. This is useful for creating a template when installing multicore fiber, or for checking aged deterioration during maintenance on existing fi ber networks. In addition to the last measured waveform, a waveform can be loaded from a fi le for use as a reference waveform.
  • Smart File Function

    Because the AQ7275 makes it easy to differentiate between measured optical fibers—even complex ones—you can add arbitrary information to file names such as measured wavelength, ID number, tape number, or comments. You can also have the ID number or tape number automatically updated and saved after each measurement.
    Trace data can be saved in SOR and CSV format. Also, you can save screenshots as BMP, JPG, or PNG files. TRB or TRD files saved on Yokogawa’s previous AQ7250 and AQ7260 models can also be loaded.
  • USB Function

    This function is useful because it can be used for external memory, printing, and communications. The AQ7275 comes standard with 2 USB1.1 compliant connector ports (types A and B).

    Type A

    Saving Files to USB Memory | Printing on an External Printer

    Type B

    Remote Control | Accessing the Internal Memory
