Optical transmission system and optical transmission method |
摘要 |
When an electric signal outputted from a signal source (101) is converted to a light signal in an electrica-optical converting portion (104), a distortion component such as secondary or tertiary distortion is caused in the light signal to deteriorate transmission quality. Therefore, the light signal outputted from the electrica-optical converting portion (104) is further intensity-modulated with the same electric signal in an external light modulation portion (106) to forcibly cause a distortion which is out of phase with and of the same amplitude as the distortion component caused in the electrical-optical converting portion (104), thereby canceling the distortion component included in the light signal. Consequently, an optical transmission system capable of high-quality optical transmitting can be realized while employing a device having equivalent performance with the conventional devices. |
