5.1 FTTH基本概念光纤到户(Fiber To The Home,FTTH,也称Fiber To The Premises)是一种光纤通信的传输方法。是直接把光纤接到用户的家中(用户所需的地方)。具体讲,FTTH是指将光网络单元(ONU)安装在住家用户或企业用户处,是光接入系列中除FTTD(光纤到桌面)外最靠近用户的光接入网应用类型。FTTH的显著技术特点是不但提供更大的带宽,而且增强了网络对数据格式、速率、波长和协议的透明性,放宽了对环境条件和供电等要求,简化了维护和安装。
5.1 FTTH Basic Concepts Fiber To The Home (FTTH, also known as Fiber To The Premises) is a method of optical fiber communication. Is the direct access to the user’s home fiber (where the user needs). Specifically, FTTH refers to installing an ONU at a home user or an enterprise user, and is an optical access network application type closest to a user except an FTTD (fiber to the desktop) in the optical access family. The significant technical feature of FTTH is that it not only provides more bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation.
