It has also been shown that this deviation is more than just addition of linear loss coefficient especially when long haul fiber optic systems with inline amplifiers are considered.

Yet, most systems exhibit dynamic behavior on their way to (or sometimes even during) the steady state that may produce a deviation in performance from that computed by steady state analysis.

The modified model yields much better prediction compared to the prediction with the original model for asymmetric systems, the mean deviation of bubble pressure decreased by more than 25 percent.
