The crosstalk and the distortion of the optical pulse due to the random polarization coupling is calculated for the birefringent optical fiber from the random mechanical bending and twist, by using the generalized expression of the coupling coefficients. A long-tailed" crosstalk pulse is found to appear as a result of the random polarization coupling. The improvement of the polarization instability from the random deformation by increasing the birefringence is discussed.
