Background: This paper provides the review of optical fiber communications and also provides the different types of disasters and different protection schemes, how to combat these disaster. In optical communication network the failure of a network caused by disasters (e.g. predictable disaster, unpredictable disaster, Intentional attacks) leads to the failure of several optical communication channels and huge data loss. Most of the previous works on optical network survivability assumes that the failures are going to occur in future, and the network is made survivable to ensure connectivity in events of failures. With the advancements in technology, the predictions of tornados, cyclone and landslides are becoming more accurate by using some early warning system.
Objective: Significant improvement in optical communication network survivability can be achieved using our proposed protection scheme in the event of major earthquake, cloud burst and landslides.
Conclusion: A large amount of data could be lost even if there is a very short disruption in the optical backbone network.
