  • Page 38 Specify a distance range value that is greater than the length of the optical fiber that you will measure. If you specify a shorter value, the AQ1200 will not be able to perform measurements properly. The longer the distance that you specify, the more time measurements will take.
  • Page 39 The maximum number of sample data points is 100,000. The shortest sample interval is determined by the distance range. Normal: The AQ1200 uses the optimum sample interval for the measurement method to perform measurements. Hi-Resolution: The AQ1200 uses the shortest sample interval to perform measurements.
  • Page 40 (excluding extremely large reflections caused by sections of the fiber such as the open end of the fiber) occur. In Hi-Reflection mode, the AQ1200 sets the optimum attenuation according to the backscattering light level for each section, and performs the measurement. Therefore, the measurement time is longer than in Hi-Speed mode.
  • Page 41 When you turn this feature on, you can prevent light from being transmitted from the AQ1200 optical pulse output port if an optical fiber is not connected to the AQ1200 or if the fiber is not connected correctly.

  • Page 42: Setting Analysis Conditions

    This phenomenon is known as backscattering. The backscattering light level setting is used when the AQ1200 calculates the return loss and total return loss.If you do not set the correct backscattering light level, the return loss and total return loss measurements will be incorrect.
