    摘要: A transmission apparatus is provided. The transmission apparatus in a transmission system that performs dispersion compensation on a transmission line includes a receiver, an information collection unit and a chromatic dispersion providing unit. The receiver receives a wavelength division multiplexing optical signal for each wavelength from the transmission line. The information collection unit collects information regarding a reception method applied to each wavelength of the optical signal received by the receiver, as reception method information. The chromatic dispersion providing unit provides respective chromatic dispersion amounts different from each other to an optical signal received using a digital coherent reception method and an optical signal received using a reception method other than the digital coherent reception method, based on the information regarding a reception method collected by the information collection unit.
