<p>PROBLEM TO BE SOLVED: To easily grasp characteristic differences of an optical fiber line resulting from a difference in an incident light. SOLUTION: The wavelength of a light pulse incident from a light pulse generating part 24 into an optical fiber line 1 of a testing object is switched automatically in a preset order by a measurement control circuit 35, a waveform data in each wavelength showing a transmission characteristic of the optical fiber line 1 is stored in a memory 32, and the waveform data are displayed collectively in the first display area of a display 22 by a waveform displaying means 41. Events detected respectively as to the waveform data by respective wavelengths are listedly displayed in the second area of the display 22.</p> |
