信息高速公路的最重要材料是光缆。而光缆的核心材料,就是光导玻璃纤维简称光纤。但是,玻璃光纤价格昂贵、材质脆,是建设信息高速公路的一大路障。据有关资料报道,一条单股玻璃光纤通讯线的成本,约100美元,而同样长度的塑料光纤,仅为10美分,但塑料光纤的最大缺点是透光度不够,不能达到预期的效果。根据这一关健问题,日本庆应大学在这方面开展研究,取得突破性进展。1994年10月于日本举
The most important material for information superhighways is fiber optic cable. The core material of the optical cable, is called optical fiber glass fiber referred to as. However, expensive glass fiber, brittle material, is the construction of an information highway a barricade. According to the information reported, a single glass fiber optic communication line costs about 100 US dollars, while the same length of plastic optical fiber, only 10 cents, but the biggest drawback of plastic optical fiber is not enough transparency, can not achieve the desired results. According to this key issue, Keio University conducted research in this area and made breakthrough progress. October 1994 in Japan
