We introduce a fully deterministic, computationally efficient method for characterizing the effect of nonlinearity in optical fiber transmission systems that utilize wavelength-division multiplexing and return-to-zero modulation. The method accurately accounts for bit-pattern-dependent nonlinear distortion due to collision-induced timing jitter and for amplifier noise. We apply this method to calculate the error probability as a function of channel spacing in a prototypical multichannel return-to-zero undersea system.
我们介绍了一种完全确定性的、计算效率高的方法，用于表征在采用波分复用和归零调制的光纤传输系统中非线性的影响。该方法准确地考虑了由碰撞引起的定时抖动导致的与比特模式相关的非线性失真以及放大器噪声。我们将此方法应用于计算一个典型的多通道归零海底系统中误码率作为信道间隔函数的情况。
