In recent years, the optical network has been developing rapidly towards high speed and large bandwidth. It carries a large number of information transmission tasks and its security issues are receiving more and more attention. Among them, the impact of high power signals on optical networks and the protection technology become the light One of the newest research hotspots in the field of network security. The gain competition attack, inter-band crosstalk attack and in-band crosstalk attack caused by high power signal in optical network are introduced. The impact of attack caused by high power signal on user signal quality in optical network is analyzed. From the attack detection and location technology, security routing protection technology summed up the high-power signal attack effect of optical network security protection technology.
