On a graph representing fiber optics measurements, where is the distance scale located?

In the context of fiber optics measurements, the distance scale is typically represented on the X-axis at the bottom of the graph. This is a standard convention in many types of data representation where the horizontal axis (the X-axis) is used to indicate independent variables, which often include distance measurements in fiber optics applications.

For instance, when analyzing parameters such as attenuation, reflectance, or insertion loss over varying lengths of fiber optic cable, the X-axis will provide the relevant distances that allow technicians to correlate performance metrics with specific lengths of fiber. This arrangement helps in visualizing how the performance, such as signal loss, changes as the distance increases.

In contrast, the Y-axis usually represents dependent variables, like signal strength or loss, which are influenced by distance. Therefore, having the distance scale at the bottom (on the X-axis) is a consistent and logical approach when interpreting the results of fiber optic tests.
