Abstract: We describe an approach to simulate the power transients in complex (branched, ring, or mesh) transparent fiber optical networks. Simulations are performed at two time scales: first, the signal power dynamics in Erbium-doped fiber amplifiers is modeled at (sub-) millisecond scale using statistical signal descriptions. Further, the teletraffic performance of the network, such as the bit error rate, can be investigated for selected time instances at nano-second to sub-pico-second time scale using a sampled signal model ('bit-level' simulation). For the detailed simulation on 'bit-level', signal information and internal states of the network components are re-used form the first simulation step at (sub-) millisecond scale. To illustrate our approach, we discuss simulations of 'higher-order' transients in a ring network.
