the following example is for you reference.


Features:1.Automatic Measurement Mode: Only by selecting the measurement wavelength, the
Measurement parameters are automatically set, and the trace data is automatically saved and
Automatically analyzed.
2.Multi-wavelength Measurement Mode: in the parameter setting, the wavelength can be
Automatically switched into the multi-wavelength measurement mode. under this mode, the
Analysis can be achieved on the attenuation state of the same fiber section under different
Wavelengths.
3.Trace Fixing Function: It can achieve the same-screen comparison and display of one trace
with another real-time trace or the trace under the average measurement, which is very useful
for the installation of multi-core fiber or the checking of the aged fiber in the optical fiber
Network already been installed.

Remarks: 1. the technical specification describes the ensured performance of the instrument when using typical PC model connector to
Measure. without considering the uncertainty caused by optical fiber refractivity.
2. Dynamic range is the data measured under the condition of the maximum pulse width and 3 minutes of average time.
Dynamic range is the data measured under the condition of 180km/20480ns/3min.
3. Measuring conditions of blind zone: reflection event is within 4Km, reflection strength < -35dB. Measured by the minimum
Pulse width.
4. Dynamic range measured when there is filter.
