摘要:随着我国互联网事业的不断发展,IPTV以及视频通信和网络游戏等高宽带业务也就应运而生。这些高宽带业务对于用户接入宽带的速度要求不断增加,现有的以CABLE MODEM以及ADSL等为主的快带接入方式已经难以适应现代用户对于高宽带、安全以及双向传输等性能的要求。这样FTTH技术作为新一代接入网技术就应运而生了,在高宽带技术更新换代之后,光纤到户成本大为降低,这也就为FTTH技术的推广使用提供了基础。

Abstract: With the development of Chinas Internet business, IPTV and video communication and network game contour broadband business also arises at the historic moment. These high broadband business users access to broadband speed requires the continuous increase, the existing to CABLE MODEM and ADSL, etc, quick take the access method has been difficult to adapt to the modern user for high broadband, security and two-way transmission of performance requirements. So FTTH as a new generation of access network technology is made, in high broadband technology renewal after, fiber to the home greatly reduce the cost, this also is to promote the use of FTTH provided the foundation. In our countrys character, FTTH fiber to the home is a kind of inevitable development trend, expected in 2012, our country will lift from coast to the mainland of fiber to the home construction upsurge.

1 FTTH技术概述
要分析FTTH技术及其应用,首先必须了解FTTH技术到底是什么。FTTH技术(FIBER TO THE HOME),就是指光纤直接迁到每一个家庭。具体来说,FTTH技术就是指光纤网络单元安装在某个具体的家庭用户出后者是某个企业网络用户处,是目前而言光接入系列中在FTTD,也就是光纤到桌面以外与直接用户最为节约近的光纤接入网络应用类型。FTTH技术与传统的CABLE MO DERM等接入方式不同,它能够提供更为高速度的宽带,很大程度上提高了网络对于速率、数据格式以及协议和波长的透明性,对供电以及环境条件的要求有所放宽,同时对于网络安装和维护也有所简化。并且FTTH技术的成本也会随着技术的发展和革新而降低,FTTH技术将普遍得到运用。
2 FTTH技术的主要特点
就目前而言,FTTH技术在日本和欧美等发达国家得到广泛的运用。之所以FTTH技术会受到普遍的欢迎和推广,主要还在于其与其他网络接入方式相比之下的优势。……
