汇聚分流器

汇聚分流器
 

一、产品描述Product Description

南京贝伦思网络科技股份有限公司汇聚分流器BLC-C系列是对互联网光纤传输线路上高速数据流进行内容清洗分类的软硬件产品,可作为电信增值业务和维护管理系统的应用前端设备,用于骨干网、城域网等高带宽以太网或SDH/SONET链路。系统能支持各种网络接口接入,可灵活编程处理各种数据流,既可串接做数据分析过滤,也可并接做分流输出。

Converging and Distributing Device BLC-C series products including hardware and software, are used to clean and classify the content of high-speed data flow on Internet optical fiber transmission lines. They can be applied in the  backbone network, metro network or high bandwidth SDH / SONET link as the application front-end equipment of telecommunication value-added services and maintenance management system. BLC-C series can support all kinds of network interface access, flexibly program and process all kinds of data flow, not only be connected in series for data analysis and filtering, but also be connected in parallel for shunt output.
