Title:
光受信装置および分散補償シーケンス制御方法
Document Type and Number:
Japanese Patent JP5169710
Kind Code:
B2
Abstract:
An optical receiver for receiving a processing modulated optical signal, the optical receiver includes a variable dispersion compensator for receiving the optical signal and for compensating chromatic dispersion of the optical signal in accordance with a predetermined chromatic dispersion value; a demodulator including a delay interferometer for receiving the compensated optical signal and for changing a phase moderation information of the compensated optical signal into an amplitude moderation information, and an optical demodulator for changing the amplitude moderation information of the optical signal into an electrical signal; a data regenerator for extracting a clock from the electric signal and for regenerating data from the electric signal by the use of the clock; and a controller for setting an optical phase to the delay interferometer and for setting the dispersion compensation value to the variable dispersion compensator.
