AV6418 OTDR is mainly used to measure FTTx network, it provides multi-functions in
one unit. AV6418 offers three measuring modes:

• manual mode (including realtime mode and average mode)
• auto mode
• dead zone mode
  • Manual measurement mode: manual mode is suitable for skilled operator who is familiar with the instrument. In this measurement mode, to get more accurate results, real-time mode or average mode can be selected if necessary.
    • In real-time mode, the dynamic changes of fiber chain can be detected timely, it is very useful when you need to observe the effect and process of fiber being spliced or connected.
    • In average measurement mode, the noise in trace can be suppressed, and the SNR (signal noise ratio)is improved, therefore，the result is more accurate. In fact, the more average times are executed, the more noise in trace is suppressed, and the longer time is spent for signal processing. In practice, the average times should be set properly according to necessity.
  • Auto measurement mode: the optimized measurement conditions are set automatically, it’s unnecessary operator to know about the complicated background knowledge and the further details of operating. In this mode, the more accurate results can be gained when proper average times are set, but it will increase the time of signal processing.
  • Dead zone mode: this mode is suitable for testing optical fiber with short distance and the optimized settings of distance range, pulse width and attenuator can be executed automatically. To get the best result, the terminal return loss should be guaranteed less than -40dB.
