摘要： Providing an optical terminating apparatus for an optical path network capable of further reducing a scale of matrix optical switches. In the drop-side optical signal terminating apparatus 10d, after one wavelength division multiplexing light selected from a plurality of wavelength division multiplexing lights transmitted via the input-side optical fibers is separated into a plurality of wavebands which constitutes the wavelength division multiplexing light, a waveband including the drop wavelength is selected from the plurality of the wavebands; the one waveband is separated into a plurality of wavelength channels which constitutes the one waveband; the wavelength to be dropped is selected from the plurality of the wavelength channels; therefore, the selectors for the waveband selection and the wavelength selection can be formed by combining compact switches to implement the colorless, directionless, and contentionless function, thereby significantly reducing the scale of the optical signal terminating apparatus 10.
