交换的功能和业务正趋于集中在少量的大中型交换局结点上,同时尽量缩短双绞线铜缆的长度,在几公里范围内,用光纤接近终端用户也成为一种趋势。目前,针对各种特定环境所用的技术多种多样。本文就有关铜缆、光缆及无线方面的技术以及阿尔卡特部分产品作一个简单的介绍。

Switching functions and services are tending to be centralized in a small number of large and medium switching nodes, and approaching end users via optical fiber cables within a few kilometers is also becoming a trend while minimizing the length of the twisted copper wires. At present, various technologies apply to different environments. Copper cable, optical fiber cable and radio access technologies and some related Alcatel products are briefly described.
