| 摘 要： | CATV系统为旅客及车站办公人员提供综合视频信号。随着数字电视的普及,越来越多的既有站房、行车公寓进行了数字信号传输模式改造。现有的改造方式利用了既有的区域网电视信号传输通道,未对传输方式进行变革,不能满足数字电视更大的数据流量。一种将ATM技术和PON模式结合的APON技术满足数字电视的传输需求,且传输距离长,适用于新建大型站房。

| Abstract: | CATV provides video signal to passengers and station staffs.More and more stations and staff dorms have been reconstructed by adopting digital signal transmission mode with the popularization of digital television.The way of common reconstruction make use of existing transfer channels without altering the mode of signal transmission,thus the demand of larger amount of data transmission for digital TV cannot be satisfied.Now,a technology called APON,which combines the technologies of ATM and PON,can meet the... |
