1. A method comprising:
obtaining a first characteristic parameter of a first optical signal and a second characteristic parameter of a second optical signal, wherein the first optical signal is a signal transmitted in a first optical fiber, the second optical signal is a signal transmitted in a second optical fiber, the first characteristic parameter is a parameter of the first optical signal with the first optical signal being affected by a vibration of the first optical fiber, and the second characteristic parameter is a parameter of the second optical signal with the second optical signal being affected by a vibration of the second optical fiber;
obtaining, based on the first characteristic parameter and the second characteristic parameter, a probability that at least one optical cable segment of the first optical fiber and at least one optical cable segment of the second optical fiber comprise a same-cable segment, the same-cable segment being an optical cable segment shared by the first optical fiber and the second optical fiber; and
determining, based on the probability, whether the first optical fiber and the second optical fiber share a cable segment.
