FTTx是光通信发展的必然趋势,也是当前光网络发展的最大推动力。FTTx用光缆根据其在网络中的不同位置,总体上可划分为馈线光缆、配线光缆、入户光缆。对这三类光缆的特点、典型的结构和技术进展分别进行了介绍。此外,具有优异弯曲性能的G.657光纤是FTTH系统的核心产品之一,对其国内外技术和标准的发展也进行了对比分析。
FTTx is an inevitable trend in the development of optical communications and is also the biggest driver of the development of optical networks. FTTx optical cable according to their different locations in the network, in general, can be divided into feeder cable, wiring optical cable, home optical cable. The characteristics of these three types of cable, the typical structure and technical progress were introduced. In addition, the G.657 fiber with excellent bending performance is one of the core products of FTTH system. The development of its technology and standards at home and abroad are also compared and analyzed.
