自从本世纪70年代光导纤维进入实用化以来,以其独特的优点,以有线的方式传输着包括音频、视频、图像、数据等等各种信息,发展极为迅速。从20世纪末到21世纪初,是有线信息传输方式从电缆向光缆过渡的一个转折时期,其发展趋势是:电缆、模拟传输——光缆、数字传输。光纤、光缆将广泛地应用在通信、电视及数据传输等领域之中。用光纤光缆进行电视视频(Video)、音频
Since optical fiber came into practical use in the 1970s, it has developed rapidly with its unique advantages of transmitting various information including audio, video, images, data and so on in a wired manner. From the end of the 20th century to the beginning of the 21st century, the transition of cable information transmission from cable to optical cable is a turning point. Its development trend is: cable, analog transmission - optical cable and digital transmission. Optical fiber, optical cable will be widely used in communications, television and data transmission and other fields. Use fiber optic cable for video, audio
