摘　　要：光纤是传输信号波形的一种介质纤维波导,在传输过程中它具有下列的优点:传输损耗小,比同轴电缆的损耗小三个数量级;通频带宽,可以10Ghz以上;光纤是绝缘体,因而不受电磁感应干扰,耐高压300kV;采用光纤传输容易实现被测信号波形与终端测量仪器的隔离与接地问题。Fiber is a kind of medium fibre wave-guide to transmit signal wave.It has several merits during transmission.First,the fiber transmission cost is low,which is 1000 times lower than coaxial-cable or more.Second,the transmission band is very broad,which can be higher than 10GHz.Third,because fiber is insulator,it will not be affected by electromagnetic influence and can afford 300kV high voltage.Forth,the problems of insulating and grounding of the terminal measurement equipment and the signal to be tested can be well solved by the fiber transmission.
