Since the improvement of amplifier and dispersion compensation technology, some well known fiber parameters, such as loss and dispersion, no longer affect the capability of communication system any longer. 由于光放大器和色散补偿技术的发展,已经使得像损耗和色散这样一些大家所熟悉的光纤参数不再对通信系统性能产生影响。
Silk fiber is a kind of natural protein fiber, has great affinity with the human skin, known as fiber queen. 蚕丝是一种与人体有着极好亲和性的天然蛋白质纤维,被誉为纤维皇后。
Bananas are known as high fiber fruits and also high in calory, hence providing energy in daily activities. 香蕉被称为高纤维水果,也高卡路里,因此提供能源的日常活动。
The passenger jet is built mostly of plastic composites known as carbon fiber, which is lighter than aluminum, and it has new wing and engine designs to make it more fuel efficient. 该客机主要是由被称为碳纤维的比铝还轻的塑料复合材料做成的,而且它具有最新的机翼和发动机设计使其更省油。
But it is well known that the fiber dispersion is a primary barrier for the short pulse generation. 然而在光纤激光器中实现短脉冲,光纤的色散参量则成了一个重要屏障。
