The optical network deploying WDM technology efficiently utilizes a single fiber's capacity, thus satisfied the increasing requirement for bandwidth. This paper shows that this kind of network in all-optical form is feasible and practical when applied in metro area, in which transparent transmission can be obtained. For the following section of this paper, we discuss the architecture of the metro all- optical network, and analyze the coordination of protection and restoration schemes between optical and electronic layer. Finally, we show the possible architecture bridging the transparency and the opacity, which is considered to be practical in the near future. And we further present the functional block of the photoelectric component-a novel transponder which is deployed in this architecture.
