FTTH网络进入加速建设期,针对FTTH建设的经济性和速度,应用于FTTH的光缆及其安装方式呈现出不同于干线网的特点,如具有小型化、密集容纤、易于跨中分接、干式缆芯等特性的光缆,以及机械连接、现场安装的连接器和预端接等连接技术。介绍了FTTH中光缆的配置与要求,并对FTTH网络中新型的光缆结构和特性及其现场安装技术进行了阐述。
FTTH network into the accelerated construction period, in view of the economy and speed of FTTH construction, the application of optical fiber cables and their installation methods in FTTH are different from the trunk network characteristics, such as a small, dense fiber, easy cross-tapping, dry Fiber optic cables and other characteristics of the cable, as well as mechanical connections, field-installed connectors and pre-termination and other connection technologies. The configuration and requirements of optical fiber cables in FTTH are introduced. The structure and characteristics of new optical fiber cables in FTTH network and the field installation technology are also described.
