摘要： A signal for each wavelength is extracted from multiplexed light signals that are wavelength-multiplexed and transmitted, and an evaluation value showing a degree of signal deterioration caused by polarization mode dispersion for each wavelength is measured. Then, the wavelength of a target of the polarization mode dispersion compensation is selected based on the evaluation value and the polarization mode dispersion compensation is implemented for only the light signal of the selected wavelength.

A dielectric multi-layer film is formed on the first face of the tapered prism positioned on an optical signal inputting side. A reflection film is formed on the second face for reflecting the optical signal inputted to the tapered prism through the first face at least once toward the first face. A non-reflection film is formed on one of the first face, the second face and the other face or faces of the tapered prism for extracting therethrough the optical signal inputted to and reflected in the tapered prism.
