A full set of double-sided power constraints are derived from the single-sided constraints at only two points of each section of a point to point optical link. It is shown that this can be obtained if the input power of the link remains within a feasible range. The two single-sided constraints provide the upper bounds for the gain values of the amplifiers at each module. Therefore, double-sided constraints at all of the points along the link can be obtained by satisfying the gain limits of the amplifiers. Furthermore, unlike the conventional way of considering a unified set of constraints for the entire link, different minimum and maximum power constraints are considered for each section of the link.
