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.
    5. Dynamic range measured when there is no filter.
