Professional maintenance Yokogawa AQ1210E optical time domain reflectometer, its common faults and causes are analyzed as follows
Fault: The test data is unstable
Reason analysis:
Optical pulse generator performance decline: The performance of the optical pulse generator may be unstable due to long-term use or environmental factors, thus affecting the stability of the test data.
Reduced detector sensitivity: Reduced detector sensitivity may cause fluctuations in the intensity of the received optical signal, which in turn affects the stability of the test data.
Environmental factors interference: Environmental factors such as temperature change and electromagnetic interference may interfere with the test data, resulting in data instability.
Failure point: Insufficient test accuracy
Reason analysis:
Calibration failure: The Yokogawa AQ1210 optical time domain reflectometer may not be calibrated regularly or there is a problem with the calibration process, resulting in reduced test accuracy.
Internal circuit failure: Aging or damage to internal circuit components can lead to inaccurate signal processing, which can affect test accuracy.
Fiber connection problems: The test fiber or connector may be contaminated, damaged, or poorly connected, resulting in reduced test accuracy.
Fault point: The test distance is not accurate
Reason analysis:
Clock circuit failure: The accuracy of the clock circuit can lead to inaccurate time measurements, which can affect the accuracy of the test distance.
Optical fiber loss calculation error: The calculation of optical fiber loss may result in an inaccurate test distance due to algorithm problems or improper parameter setting.
Instrument setting error: The user may not set the test parameters correctly, such as pulse width, average times, etc., resulting in an inaccurate test distance.
