有线电视网络分支分配器的改进

The Improvement of the Branch Distribution Implement of Cable TV Network

为加强有线电视网络建设和用户管理 ,在城区建成了一套完整的可寻址管理系统。由于原系统安装的器件是不过流的 ,而新系统需用的是各种类型的过流器件 ,为满足工程需要 ,应用电感、电容串并联原理 ,对原不过流器件进行改装 ,通过测试 ,达到技术指标 ,经过使用 ,性能良好 。

In order to reinforce the construction of CATV network and the management of customer,the department had set up a suit of integrated magnagement system which can circulate the site.Parts of the apparatus which were installed before can't be current,while all kinds of current apparatus must be used in the new system.To meet the requirements of the project,apply the series and parallel connection principle of inductance and capacitance to refit the former apparatus.By testing,it reaches the technique index and has superperformance and cheap cost.
