4.1.3 High Slope of Curve
As in the upper right figure, the slope of this section is obviously
larger, which indicates that the quality of this section of optical fiber is
not good and the loss is large.
4.1.4 No reflection peak at the far end of the curve
As shown in the lower right figure, there is no reflection peak at the
tail of the curve, which indicates that the quality of the distal end of the
optical fiber is not good or that the distal end of the optical fiber is
broken here.
