产品描述 Description

图片6.pngGYTA53光缆的结构是将250µm光纤套入高模量材料制成的松套管中,松套管内填充防水化合物。缆芯的中心是一根金属加强芯,对于某些芯数的光缆来说,金属加强芯外还需挤上一层聚乙烯(PE)。松套管(和填充绳)围绕中心加强芯绞合成紧凑和圆形的缆芯,缆芯内的缝隙充以阻水填充物。涂塑铝带(APL)纵包后挤一层聚乙烯内护套,双面涂塑钢带(PSP)纵包后挤制聚乙烯护套成缆。

The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.
