In this article, a fast prediction method for statistical characteristics of cable bundle crosstalk, allowing accurate description of cable bundle crosstalk under nondeterministic geometric arrangement, is introduced. Different from the traditional flexible cable model, this method uses the Hermite interpolation method to simulate the spatial pose of the cable bundle according to the structural characteristics of the cable bundle in the actual situation. The condition of the Hermite interpolation method is the known node function value and the first derivative value, using random variables instead of known nodes, can be used to simulate the binding points in the cable bundle and the geometric uncertainty of the bundle. The Hermite interpolation formula under random node $\xi_{i}$ is as follows.
