Abstract
The present application discloses a data secrecy method for a submarine cable system with a failure and a submarine cable system. The method includes: determining a first disaster tolerance set in response to that a failure occurs to a first branch; and replacing a target optical signal in a first optical signal with a virtual optical signal. The first branch is any branch in the submarine cable system. The first disaster tolerance set includes at least one wavelength used for optical signals for transfer from a first terminal station to the first branch. The first optical signal is an optical signal output from the first terminal station. The target optical signal includes optical signals corresponding to the respective wavelengths in the first disaster tolerance set. The virtual optical signal is an optical signal that does not carry data content.
