光纤通讯是以光波为载体，光纤为传输媒质的通讯方法。1965年之前光纤已在学技术中得到使用，但仅限于短距离传输图象，衰减为1000dB/km

(Optical fiber communication is a communication method in which light waves are the carrier and optical fibers are the transmission medium. Before 1965, optical fiber has been used in science and technology, but it is only limited to transmit images over short distances, and the attenuation is 1000dB/km)
