接入网用光纤光缆技术的发展

Progress on Optical Fibers and Cables in Access Networks

云计算、物联网等新概念的出现进一步推动了全光网的快速发展,其中光网络的接入技术和产品成为光纤技术当前最为热门的话题之一。本文对接入网用的单模光纤特别是弯曲损耗不敏感的单模光纤的研究进展进行了介绍,同时对接入网用光缆的技术和产品进行了分析,详细介绍了几种典型的馈线光缆、配线光缆和入户光缆。

Recently, such new conceptions as Cloud Computing and the Internet of Things greatly accelerate the developing of all-optical networks, and therein optical fiber products and technologies in access networks become one of the hot topics for the society. In this paper, the progress and devel- opment of single-mode optical fibers and relevant technologies, especially low bend lost fibers were presented, cables and relevant technologies used in access networks were analyzed, and several typical optical feeder cables, optical distribution cables and optical indoor cables were particularly introduced.
