OPTICAL TRANSMISSION DEVICE |
| 摘要 |
An optical transmission device is provided to efficiently carry out dispersion compensation at an OADM control time of an optical signal in which different bit rates are intermingled. When there are k kinds of bit rates of an insertion optical signal, i.e., an optical signal to be inserted, an insertion control unit (12) connects k (<N) input ports out of N input ports, transmits the insertion optical signal to the k input ports and carries out insertion control. A branch control unit (13) connects m (<M) output ports out of M output ports and carries out branch control of an optical signal transmitted from the m output ports. Dispersion compensation to compensate wavelength dispersion corresponding to every bit rate is set at each of k side lines (L1-Lk) connecting k input ports of an N X M selection switch (11) with the insertion control unit (12). The insertion control unit (12) selects a side line to carry out the dispersion compensation of the insertion optical signal and transmits the insertion optical signal to the N X M selection switch (11) through the selected side line. |
