Patent number: 6882410Abstract: A filter processing system making it possible to be able to set a frequency pass-band automatically and to provide the optimum filter to an input signal. A filter processing method of an output signal of an Optical Time Domain Reflectometer (OTDR) in a chromatic dispersion distribution measuring apparatus is disclosed. The filter processing method includes establishing measuring-condition parameters, generating an ideal signal waveform based on previously established chromatic dispersion values and the measuring-condition parameters, and providing correlation results between the ideal signal waveform and a filter input signal. The method also includes comparing the correlation results to a threshold value to generate a minimum chromatic dispersion value and a maximum chromatic dispersion value, and performing filter processing for the output of the OTDR based on the minimum chromatic dispersion value and the maximum chromatic dispersion value.Type: GrantFiled: January 16, 2003Date of Patent: April 19, 2005Assignees: Ando Electric Co., Ltd., Kyusyu Ando Electric Company LimitedInventors: Yoshimitsu Asahina, Takao Suzuki, Shoichi Aoki, Yoshiaki Ohtsuka
