comsis, which stands for communication systems interactive software, is a computer-aided-design tool based on a time approach. It allows the design, analysis, and performance optimization of optical transmission systems by use of various optical devices. comsis allows scalar or vectorial simulations, depending on whether the polarization is taken into account. An overview concerning the optical component models is given. A new model of an erbium-doped fiber amplifier allows the user to describe the amplifier through either physical or system parameters by using silicate or fluoride glass fibers or any other material, provided the user can give a file that contains the amplifier's characteristics. The new model of a single-mode fiber allows the user to describe chromatic dispersion through a constant, a function, or a file (given by the user) and to take optionally into account the Kerr and the Raman effects and the polarization-mode dispersion. The simulation tools that are used to characterize the quality of an optical transmission system are also presented. To show the system's full range of capabilities in the optical domain, we describe examples of wavelength-division-multiplexing and soliton-transmission systems.
Comsis代表通信系统交互式软件，是一种基于时间方法的计算机辅助设计工具。它允许通过使用各种光学器件对光传输系统进行设计、分析和性能优化。Comsis允许进行标量或矢量模拟，这取决于是否考虑偏振。文中给出了关于光学元件模型的概述。一种新型掺铒光纤放大器模型允许用户通过物理参数或系统参数来描述放大器，可使用硅酸盐或氟化物玻璃纤维或任何其他材料，前提是用户能够提供包含放大器特性的文件。单模光纤的新型模型允许用户通过常数、函数或文件（由用户提供）来描述色散，并可选择考虑克尔效应、拉曼效应和偏振模色散。文中还介绍了用于表征光传输系统质量的仿真工具。为了展示该系统在光领域的全部功能，我们描述了波分复用和孤子传输系统的示例。
