摘要

A transfer function or an inverse transfer function of an optical transmitter (7) of a transmission unit (1) is estimated from first data acquired by a reception unit (3) when a first known signal is transmitted from the transmission unit (1) to the reception unit (3) of the optical transceiver, and a temporary transfer function or a temporary inverse transfer function of an optical receiver (9) of the reception unit (3). A transfer function or an inverse transfer function of the optical receiver (9) is estimated from second data acquired by the reception unit (3) when a second known signal is transmitted from the transmission unit (1) to the reception unit (3), and the estimated transfer function or the estimated inverse transfer function of the optical transmitter (7).
