Abstract
A line measurement method is provided. The method includes obtaining data of relation between a line length and an insertion loss phase radian, and obtaining data of relation between the line length and a loop attenuation parameter value; obtaining four length values from the data of relation between the line length and the insertion loss phase radian, and defining a length range to obtain the first and the second length range; and determining the boundary of the second length range close to a midpoint of the first length range, using a line length value corresponding to the boundary close to the midpoint as a measured line length, and using a line diameter corresponding to the line length value as a measured line diameter.
