ABSTRACT:
An optical demultiplexing device used in an optical monitoring device includes an input port and an output port unit including a plurality of ports, and separates a WDM light of plural channels, which is input from the input port, for each wavelength to output to the output port unit. The output port unit includes a plurality of output port sets each of which includes at least two individual output ports as a set, and crosstalk between adjacent individual output ports in a single output port set is larger than crosstalk between adjacent individual output ports belonging to different output port sets.
