Safety and Survivability in FTTH network is an important issue. It has been discussed in optical network by earlier studies. When a network transfers more data, the total interruptions due to network failure or attack become important issue for consideration. Therefore, many authors proposed the new technique and method to give the protection and restoration the fiber region area especially scattered placement to become a good signal transfer without failure. Most of the proposal chooses the alternative path line to carry the optical signal when the failure is occur in the other line. Two major fibers placed on two lines which are located in the tree and ring network. Every linear path (tree lines), the working lines would be duplicated with the protection line.
