光纤通常被用于传输光信号,但光纤还用来传输光能量和作为传感器的介质。从理论上讲,光可以代替电来传递信息和能量。但是当光纤的应用环境从长距离通信变为工业控制、变为医疗卫生、汽车、火车、飞机、宇宙飞船和石油勘探时,对光纤的要求,尤其是对光纤在不同环境下的要求会更苛刻。具 Optical fiber is usually used to transmit optical signals, but optical fiber is also used to transmit optical energy and as a sensor of the media. In theory, light can replace electricity to transmit information and energy. However, when fiber optic applications change from long-distance communications to industrial control to medical, automotive, train, aircraft, spacecraft and oil exploration, the requirements for optical fibers, especially for optical fibers in different environments, will be even greater harsh.
