本文提出一种光缆设计的全新概念。将光纤包扎成束并以色标带作为识别标志,把若干个光纤束置于一直径较大的管子中形成缆芯,再用上加强型聚乙烯护套形成光缆。按这种思想设计的光缆十分轻巧而且有极好的光学性能与机械性能。这种光缆可用于ATT通信系统的长距离网络或州内通信网,也可以用于办公室内的千线及用户环路。 This paper presents a new concept of fiber optic cable design. The optical fiber bandaged into bundles and color bands as identification mark, the number of fiber bundles placed in a larger diameter tube to form a cable core, and then use the reinforced polyethylene sheath to form a cable. Cables designed according to this concept are very lightweight and have excellent optical and mechanical properties. This cable can be used for ATT communications systems, long-distance network or state communications network, can also be used for the office of the trunks and user loops.
