AV6416 Palm OTDR is mainly used to measure FTTx network, it
provides a low cost solution for users. AV6416 offers three
measuring modes: manual mode (including real time mode and average
mode), auto mode and 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
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.
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 is 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
Auto measurement mode: the optimized measurement conditions are set automatically, it´s
unnecessary to 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
