基于VC++的光纤通信中继距离设计软件系统

Software System in Designing Fiber Communication Relay Distance based on VC++

损耗和色散是影响光中继距离的主要因素,采用最坏值设计法,利用VC++高级语言建立损耗和色散计算处理模型,通过计算机仿真,实现光传输设计自动化。该系统能实现参数设定,参数查询,中继距离计算分析,中继距离的确定等功能,并可以实现以ITU-T G.957推荐标准具体讨论传输距离的问题。

Attenuation and dispersion are two main factors effecting optical fiber repeater distance. This paper adopts the worst value design method to establish the calculation and handling model of attenuation and dispersion system with VC ＋＋, and implements automation of optical transmission design through computer simulation. The system can provides the functions of parameters setting, parameters acquiring, computing and analyzing of repeater distance and determining of repeater distance automatically,and find the correlative parameters from the database with ITU-TG. 957 recommending standards.
