First, the article analyses the current situation of the Wide Band transmission optical network of Metro and put forward its target of next development. And it continues to talk about the key technology of the Wide Band transmission optical network of Metro: optical caber, MSTP, DWDM, RPR and make comparison with them. It offers the general plan of construction of the Wide Band transmission optical network of Metro.
