摘要
本文根据第53届(2004)国际线缆会议(IWCS)发表的论文综合报道各国在微光缆方面的最新发展。这种发展方向有从分散向比较集中的趋势。按照光纤的芯数,分别采用光纤单元或者松管结构(层绞松管或中心松管),也可以将这两者结合起来。这些发展对于今后微光缆与安装微光缆所用微管道的标准化是重要的参考。
The paper presents the latest developments of micro-cables in various countries. These information are compiled from the 53^nd IWCS/FOCUS of 2004. The development trends seem to be somewhat converged. According to the number of fibers in the cable, fiber units or loose tubes ( stranded or central) cables are mostly used. A combination of these two techniques is also reported. Such developments will be an important reference for the future standardization of micro-cables and micro-ducts.
