<p>The present invention provides a reconfigurable optical add/drop multiplexing device for enabling totally inresistant wavelength irrelevance, wherein a dropping unit is used for separating optical signals of multiple wavelengths in direction 1~X which are broadcast inputted from the line direction, switching optical signals of multiple wavelengths in direction 1~X to corresponding any output port through multiple N×N optical switches, and sending the received optical signals to corresponding Receivers (RX) after combining the signals through the corresponding K×1 couplers/optical switches. An adding unit is used for broadcasting optical signals which are sent from Transmitters (TX) to multiple N×N optical switches through N 1×K couplers /optical switches, switching optical signals to corresponding any output port through each optical switch, and combining optical signals corresponding in direction 1~X to send to the line direction. Wherein, X is an integer and X>=2, and K and N are all integers. The present invention can enable totally inresistant wavelength irrelevance in adding and dropping.</p> |
