<p>An embodiment of the present invention relates to a WDM optical transferring system using a two-way hopper structure. A technical objective to be solved is to reduce the loss of signal energy in the branching and multiplexing operation of an optical signal through a two-way hopper structure and to perform high speed light transmission. For this, an embodiment of the present invention includes relates to the WDM optical transferring system including a hopper structure which includes an alignment lens and an optical connector connected to an optical fiber on the outside opposite surface of a housing, is formed between the alignment lens and the optical connector inside the housing, and totally reflects light transmitted from each to the optical fiber in each direction. The two-way hopper structure includes a first hopper type lens formed in the light connector, at least two second hoper type lenses formed in the alignment lens, and an index waveguide formed between the first hopper type lens and the second hopper type lens. The internal diameter of the end part of the first hopper type lens is larger than the internal diameter of the end part of the second hopper type lens.</p> |
