1·They first were observed in a boat canal in 1834 and now are used in optical fiber communications.
它们在1834年在一条运河船中被观察到，现在被用于光纤通讯。
2·In 197o, researchers at Corning Glass Works were able to produce a kilometer-long ultrapure optical fiber.
1970年，康宁玻璃厂的研究者们能生产出了光可以穿行1千米的超纯光纤。
3·Using that method, they were able to send data over a 50-kilometer length of optical fiber at 26 terabits per second.
用这个办法，研究人员能通过50公里长的光纤每秒发送26t的数据。
4·Electronic data piped into one chip is converted into laser light that travels down an optical fiber and is transferred back into electrical signals a few fractions of a second later.
电子信号进入集成电路后被转换成激光，由光纤传出，在不到1秒的短时间后重新被转换成电子信号。
5·"It's not just a case of whip out the electrical wires and replace them with optical fiber," says Bergman.
“这并不仅仅是展示用光纤替代电线”，Bergman说。
