摘要
HFC网络管理系统对于户外光站的管理是利用前端控制器与应答器通过FSK调制通信方式来实现的,温差环境的变化和网络噪声对通信影响较大,利用数字解调技术可解决这一问题。介绍HFC网络管理系统在东北地区的应用。
HFC network manager system uses head end and responder to achieve the management of out plant by FSK.Large temperature difference and net noise will make big effect on the communication.This article supplies an idea that using the digital demodulation technology to achieve the application of HFC network manager system in Northeast China.
