Evaluation apparatus for an optical fiber transmission line

An evaluation apparatus for an optical fiber transmission line being a measurement target optical fiber formed by connecting a plurality of optical fibers each having a predetermined unit length in series, comprising:

• a measurement execution section for executing a measurement with a function equivalent to a function of an optical time domain reflectometer (OTDR) that measures a splice loss, a return loss, and a unit length loss each indicating various evaluation characteristics of the measurement target optical fiber in response to a return light of an optical pulse input to the measurement target optical fiber;
• a typical value extraction section for extracting data indicating maximum values of the return loss and the unit length loss, as typical values, from measured data indicating the various evaluation characteristics of the measurement target optical fiber measured by the measurement execution section, while simultaneously extracting data indicating a maximum value of the splice loss which is an absolute value;
• and
• a display section for displaying section for displaying the data of the maximum values of the return loss and the unit length loss extracted by the typical value extraction section as the typical values indicating the various characteristics of the measurement target optical fiber and the data of the maximum value of the splice loss which is the absolute value, in such a manner that items of the various characteristics respectively correspond to the data of the maximum values.
