A procedure is described that allows one to solve the evolution equations in birefringent optical fibers by using repeated diagonalization. With this approach several practical problems are solved in a unified evolution in twisted fibers, sinusoidally rocked fibers, and fibers with randomly varying way. Included are last case it is shown that a phenomenological model described by Poole and others birefringence. In the applies to fibers whose axes of birefringence can take on any orientation.
