A bit error rate estimation method for optical fiber transmission systems employing all-optical 2R regenerators is presented. The method is based on the linearization of the nonlinear transfer function of the regenerators in three sections. Using this linearized three-section model, the impact of 2R regeneration on the system performance as a function of the extinction ratio, the clamping factor, and the steepness of the transfer function is studied.
