“…6. Such a fast power drop may be seen as the worst-case scenario when a fusion splice is breaking [8]. Our investigations show that the optimal choice of controller parameters differs for single EDFAs and EDFA cascades.…”

͑Doc. ID 82678͒ We report our investigations on the impact of transients stemming from channel reconfiguration or network failure. Erbium-doped fiber amplifier (EDFA) gain dynamics are considered by an average-inversion-level model. The simulation model is also verified by laboratory experiments. In extensive simulations, optimal sets of parameters for an electronic EDFA gain controller have been determined. We show that better results can be obtained if the gain controller is optimized for a chain of EDFAs and not a single amplifier only. Additionally, an efficient simulation methodology to calculate the combined bit error ratio (BER) is presented by coupling simulations of transient phenomena with bit-based simulations incorporating nonlinear fiber effects.

“…In contrast, fibers also have disadvantages, the main ones being: the high initial cost of implantation, and the limitation of optical power due to non-linear effects and due to the risk of "fiber fuse". Despite their high reliability, optical fibers can sometimes be damaged by a variety of causes [44,45]. On land, fibers can be damaged due to works, storms, or accidents, and, in the ocean, fibers can be disrupted by ship anchors, trawls used by fishing boats, marine animals, especially sharks which can chew the protection of the optical fibers, and natural disasters.…”
