Multimode concatenation modal group analysis

A multimode concatenation model is derived using the link mode power distribution and fiber mode group delay times. The model is used deterministically to predict the bandwidth length exponent γ for seven concatenations. γ depends directly on the amount of correlation existing among the fibers' mode group delays. Under the assumption that the fiber ensemble is stationary and satisfies ergodicity conditions, we are able to evaluate an ensemble-γ. It can be used statistically to estimate the concatenation-γ.
