Title: Optical transmission method and device
Inventor: HIROOKA TOSHIHIKO
IPC: H04B10/2525
Filed: 2003-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To compensate waveform distortion by using characteristic that, even if every linear distortion occurs on a time base, a spectrum shape is perfectly preserved.  <P>SOLUTION: An optical pulse which has been transmitted via an optical fiber transmission path 2 from an optical pulse transmitter 1 is transmitted. An optical Fourier transforming device 3 compensates the waveform distortion by linear effects in the optical fiber transmission path 2 by making the optical pulse incident, performing optical Fourier transformation with the optical pulse on the time base onto a frequency axis, replacing frequency with time, and reproducing the frequency spectrum of the optical pulse on the time base. A photodetector 4 obtains the pulse waveform before transmission by the optical fiber transmission path 2 by receiving the optical pulse from the optical Fourier transforming device 3 and transforming this to an electrical signal.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
