In this paper we report a laser fiber couple system, by which the output power from the fibertip can be adjusted according to the requirement of the actual investigation.
为适应该项研究的需要，设计了会聚透镜与光纤耦合器的距离可以精确调节的耦合系统。

The bacteria are housed in the tip of a fiber-optic cable, which dangles in the drinking-water supply.
这种细菌被安置在伸入饮用水中的光纤头上。
