OPTICAL TRANSMISSION DEVICE AND OPTICAL RECEPTION DEVICE |
| 摘要 |
An optical transmission device includes a division unit that divides transmission data into a plurality of data and outputs the plurality of data, a frequency conversion unit that shifts a frequency band of the divided transmission data so that the frequency bands of the divided transmission data do not overlap each other and outputs the divided transmission data whose frequency band is shifted as a modulation signal, and an optical modulation unit that modulates an optical carrier with a signal in which the modulation signals are added and outputs the modulated optical carrier as a signal light. |

1. An optical transmission device comprising:
a division unit that divides transmission data into a plurality of data and outputs the plurality of data; a frequency conversion unit that shifts a frequency band of the divided transmission data so that the frequency bands of the divided transmission data do not overlap each other and outputs the divided transmission data whose frequency band is shifted as a modulation signal; and an optical modulation unit that modulates an optical carrier with a signal in which the modulation signals are added and outputs the modulated optical carrier as a signal light. |
