<P>PROBLEM TO BE SOLVED: To provide a system for optically compensating wavelength dispersion while receiving optical signals at different bit rates. <P>SOLUTION: An interval between an optical transmission terminal station and an optical relay node, an interval between optical relay nodes, an interval between the optical relay node and a reception terminal station, and an interval between the optical relay node and a CN / OADM / HUB node are selected for first dispersion compensation intervals, an interval between the optical transmission terminal and the CN / OADM / HUB node, an interval between the CN / OADM / HUB nodes, and an interval between the CN / OADM / HUB node and the reception terminal station are selected for second dispersion compensation intervals, dispersion is compensated so that residual dispersion takes a prescribed negative value in the first dispersion compensation intervals and dispersion is compensated so that residual dispersion takes a prescribed positive value in the second dispersion compensation intervals. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
