摘要
光纤放大器的出现解决了衰减和损耗对光网络传输速率与距离的限制。掺铒光纤放大器(EDFA)的使用,使超高速、超大容量、超长距离的波分复用传输、全光网络传输、光纤有线电视(CATA)系统、光孤子传输等成为现实。
The emergence of optical fiber amplifier solved the restriction of attenuation and loss for optical network transmission rate and distance. Due to the use of erbium-doped optical fiber amplifer （EDFA）, high speed, super capacity, long distance WDM transmission, all-optical network transmission, optical fiber cable television （CATA） system and optical soliton transmission became reality.
