澳大利亚只有1700万居民,但国土十分辽阔,其面积几乎与美国相当。然而,60%以上的人口居住在6个大城市:阿德雷德、布利斯班、坎培拉、墨尔本、伯斯和悉尼,使得澳大利亚成为世界上城市化程度最高的国家,同时也是人口密度最低的国家。由于人口大部分居住在几个大城市,各大城市相距遥远,所以,国家垄断的澳大利亚通信公司迅速采用光纤通信,1982年建成首条多模光纤线路。到1990年,大部分城市都有了综合性单模光纤网络系统,已铺设的光纤在100万公里以上。
Australia has only 17 million inhabitants, but its territory is vast and its area is almost the same as that of the United States. However, more than 60% of the population lives in 6 major cities: Adelaide, Brisbane, Canberra, Melbourne, Perth and Sydney, making Australia the most urbanized country in the world and also a population The country with the lowest density. As the majority of the population lived in several large cities and the major cities were far apart, the state-monopolist Australian Communications quickly adopted optical fiber communications and completed its first multimode fiber-optic line in 1982. By 1990, most cities had a comprehensive single-mode optical fiber network system, with more than one million kilometers of optical fiber laid.
