Fiber transmission penalties due to nonlinearity and amplified-spontaneous-emission (ASE) noise are presented. ASE noise results from channel drop/add erbium doped fiber amplifier (EDFA) gain transients in 10-20 EDFAs with 32 WDM. The system model consist of 40-km spans of either standard single mode or dispersion-shifted fiber. Each span is followed by an EDFA and a long-period fiber grating for EDFA gain spectrum equalization. System performance is evaluated by calculating the Q factor of each individual channel using the averages and standard deviations of 1 s and 0 s within the central T/10 portion of each bit. Results reveal that transient penalties depend upon the data rate, number of channels, and fiber type.
