引言: 根据与邮政局的合同在一九七三年试验并评价了基于扁平电缆概念的光缆设计,其中光纤位于中心,两侧放置张力增强元件。本文所述之光缆其特点是,光纤衰减低、尺寸很小、光纤带保护层不会引入微小畸变、图1表示其结构。
Introduction: According to the contract with the Post Office, the optical fiber cable design based on the concept of flat cable was tested and evaluated in 1973 with the optical fiber in the center and the tension enhancing elements placed on both sides. The fiber optic cable described in this paper is characterized by low attenuation and small size of the optical fiber. The optical fiber with the protective layer will not introduce minor distortion. Figure 1 shows its structure.
