ABSTRACT:
An object of the present invention is to provide an optical branching and insertion apparatus with which the damage location can be searched for in all sections when a damage location is searched for in an optical transmission system in which an optical branching and insertion apparatus has been installed. The present invention provides an optical branching and insertion apparatus comprising a filter for reflecting light of a specific wavelength, a first optical circulator operatively connected to one side of the filter, outputting to the filter first light inputted from a first transmission path, outputting to a second transmission path the light of the specific wavelength reflected from the filter, and outputting to the first transmission path second light inputted from the second transmission path and a second optical circulator operatively connected to the other side of the filter, outputting to the filter third light inputted from a third transmission path, outputting to a fourth transmission path the light signal of the specific wavelength reflected from the filter, and outputting to the third transmission path fourth light inputted from the fourth transmission path.
