摘　　要：为了有效地传输不同波长粒度的业务,对多粒度光网络波带组合进行了研究。首先介绍了多粒度光网络的模型和光交叉节点,并在此基础上分析了多粒度交叉连接结构的两种结构,单层和多层多粒度交换结构。结合多粒度的交换结构,给出了几种波带组合策略,并对这些策略进行了分析和比较。In order to effectively transmit the different wavelength granularity services, how combine waveband in multi-granularity optical network is studied. First, it introduces the model and optical cross- connect in multi-granularity optical network. On the basis of the model and optical cross-connect, two kinds of multi-granularity cross-connect structure are analyzed based on single and multi-layer structure; combined with multi-granularity cross-connect structure, the policies of waveband combination are proposed, and the policies are analyzed and compared.
