英文摘要： A novel scheme on recognition of optical spectral amplitude code (SAC) labels by applying coherent detection is proposed; 112 Gb/s coherently detected polarization muxed (PolMux) QPSK payload is carried by SAC labels, in order to demontrate the received qualities and transmission characteristics of label/payload in high speed coherently detected SAC labeling system; to obtain better spectrum efficiency, the concept of implicit label is applied in our proposed system, and its transmission performance and practicability will be demonstrated; based on current label routing scenarios, label stacking routing scheme is studied, the correnponding SAC label switching core node is built up to demonstrate the switching performance of our proposal; at last, the experimental demonstration of above proposed schemes will be accomplished. The results and achievements of this project will establish the theoretical and experimental foundation on domestic high speed all optical label switching system, and also promote the development of optical switching technology in our country.
