光纤信号源IP化传输接收系统的设计与实现

Design and Implementation of IP Transmission and Reception System for Optical Fiber Signal Source

在有线前端机房为发射台传送央视光纤信号源的旧系统即将淘汰,并且有线前端机房信号传输已经IP化的大背景下,本文介绍了采用"交换机+解码器"的模式对信号源光纤传输与接收系统进行更新重建的设计方案,该方案实现了央视光纤信号源稳定可靠的接收。

Nowadays the old system is about to be eliminated,which transmits CCTV optical fiber signal to the transmitter from the cable television headend.And the signal is mainly transmitted through IP network in CATV headend.In the above background,the paper introduces the scheme of"switch+decoder"to reconstruct the optical fber transmission and reception system,which realizes the stable and reliable reception of CCTV optical fber signal.
