OPTICAL TRANSMISSION SYSTEM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an optical transmission system capable of keeping flat passing characteristics even inside an optical signal modulation band. <P>SOLUTION: A spectrum inside a modulation band for each channel of branched optical signals is monitored, the non-flatness of the passing characteristics of a transmission line is detected from the spectrum and thus the non-flatness to the optical signals is compensated. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
