The invention relates to a networking method for realizing the integration of higher order ROADM. The multi channel signal through low order adjustable micro ring filter grade filter, reduce the number of channels in a step by step, using limited modulation bandwidth, hierarchical modulation to achieve multi-channel signal ROADM, which can realize the optical channel multiplexing number is far more than the modulation bandwidth of filter can be adjusted. At the same time, in order to reduce the loss to be able to cascade more micro rings, the structure of the waveguide intersection and the coupling structure of the waveguide and the optical fiber are optimized. By the invention, the number of reconfigurable wavelengths can be much larger than that of ordinary networking methods.
