Paper Abstract

A new type of the intelligent real-time protection device is developed, which is supposed to better adapt to the physical layer protection of the mesh optical network. By means of converting the optical signal into the electric ones, the real-time online optical power data of the optical fibers are sampled and processed by the protection device, so the working state of the mesh optical network is obtained. By communicating with each other, the protection devices placed at each node of the mesh optical network can figure out the backup lightpath of each primary fiber in advance, and then a backup lightpath route table will be dynamically established and maintained by each protection device. Whenever the failure of the primary fiber occurs, the protection device will immediately switch to the backup lightpath by driving the optical switch matrix according to its backup lightpath route table. The intelligent real-time protection device for mesh optical network is a kind of real unattended intelligent real-time online monitoring and protection device for the physical layer of optical network, which is enabled to meet the requirement of the development of the mesh optical network. So the transparent uninterrupted communication of the mesh optical network could be achievable by applying the proposed intelligent real-time protection device.
