| titleOfInvention | Optical data transmission system |
| abstract | [PROBLEMS] To appropriately perform pre-equalization capable of canceling waveform distortion of a signal received on a receiving side on a transmitting side. An optical data transmission system includes optical transceivers at both ends of an optical fiber. Each optical transceiver has an optical receiver and an optical transmitter. The optical receiving apparatus measures the waveform distortion of the main signal demodulated after receiving the optical signal and estimates the waveform distortion information, and the waveform distortion information estimated in the same manner as the above estimation in the other optical transceiver. Is decoded after receiving the optical signal from the other side. The optical transmission apparatus performs waveform distortion indicated by the waveform distortion information decoded by the decoding unit 63 and the multiplexing unit 42 that multiplexes the waveform distortion information estimated by the estimation unit 65 and the main signal transmitted to the other side. The pre-equalization unit 44 that pre-equalizes the multiplexed main signal so as to cancel, and the polarization is modulated with the multiplexed signal including the pre-equalized main signal and the estimated waveform distortion information. And an E / O converter that converts the optical signal. [Selection] Figure 2 |
