Abstract

A simulation strategy suitable for performance assessment of long-haul high-bit-rate direct-detection systems is presented. Particular consideration is given to the interaction with fiber dispersion of laser modulation phenomena such as frequency chirp and patterning which exhibit complex nonlinear data dependence. The nonlinear modulation response of the laser transmitter is taken into account by using pseudo-random data sequences to estimate the dispersion-induced performance degradation. The dependence of the modulation and dispersion-induced penalties on the extinction ratio of the laser emission is shown for the specific case of 4 Gb/s NRZ modulation and a total dispersion L*D=1 ns/nm. With this approach, the implications for system performance of the laser operating point, modulation format used, receiver filter bandwidth, and timing acquisition imperfections are investigated, and some performance limitations are indicated.<>

高速直接检测光纤通信系统的建模与仿真

提出了一种适合长途高比特率直接检测系统性能评估的仿真策略。特别考虑了频率啁啾和图形等具有复杂非线性数据依赖性的激光调制现象与光纤色散的相互作用。考虑了激光发射机的非线性调制响应，采用伪随机数据序列来估计色散引起的性能退化。在4 Gb/s NRZ调制和总色散L*D=1 ns/nm的特殊情况下，给出了调制和色散诱导惩罚与激光发射消光比的关系。通过这种方法，研究了激光操作点、调制格式、接收机滤波器带宽和时序采集缺陷对系统性能的影响，并指出了一些性能限制。
