Title:
光伝送システム
Document Type and Number:
Japanese Patent JP5181770
Kind Code:
B2
Abstract:
An optical transmission system capable of efficiently reducing waveform distortion of an optical signal. A transmitting-side distortion compensation coefficient storage (1a) of a transmitting station (1) stores transmitting-side distortion compensation coefficients for compensating for waveform distortion of an optical signal to be transmitted to a receiving station (2). A transmit signal processor (1b) performs distortion compensation on the optical signal on the basis of a suitable transmitting-side distortion compensation coefficient stored in the transmitting-side distortion compensation coefficient storage (1a). A transmitter (1c) transmits the distortion-compensated signal to a transmission path (3). A receiver (2a) of the receiving station (2) receives the optical signal from the transmission path (3). A receiving-side distortion compensation coefficient storage (2b) stores receiving-side distortion compensation coefficients for compensating for waveform distortion of the optical signal received by the receiver (2a). A received signal processor (2c) performs distortion compensation on the received optical signal on the basis of a suitable receiving-side distortion compensation coefficient.
