·产品描述Description

GYFTY53 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。缆芯的中心是一根非金属加强芯（FRP），对于某些芯数的光缆来说，非金属加强芯外还需要挤上一层聚乙烯（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。缆芯外挤上一层聚乙烯内护套，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 highmodulus plastic. The tubes are filled with a water-resistantfilling compound. A Fiber Reinforced Plastic (FRP) locates in thecenter of core as a non-metallic strength member. The tubes (andfillers) are stranded around the strength member into a compact andcircular core. Then the cable core is covered with a thinpolyethylene (PE) inner sheath, which is filled with jelly toprotect it from water ingress. A layer of water-blocking materialis applied around the cable core to prevent water ingress all thesame. After a corrugated steel tape armor is applied. the cable iscompleted with a PE outer sheath.
