gyty53 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 high modulus plastic. the tubes are filled with a water-resistant filling compound. asteel 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 thestrength member into a compact and circular cable core. the cable core is filled with the filling compound to protect it from water ingress, over which a thin pe inner sheath is applied. after thepsp is longitudinally applied over the inner sheath, the cable is completed with a pe outer sheath.
