GYFTY 光缆的结构是将单模或多模光纤套入由高模量的聚酯材料做成的松套管中，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的圆形缆芯，缆芯内的缝隙
充以阻水填充物，缆芯外挤制聚乙烯护套成缆。
GYFTY cable structure is the single mode or multimode fiber into the high modulus of the polyester material made of
loose tube, casing filled with anti
Water compound. The core of the cable core is a non metal reinforced core (FRP), for some of the core number of
optical fiber cable, the non metal to strengthen the core to be extruded on a layer of polyethylene (PE). Loose tube
(and filled rope) around the center to strengthen the core of the core to strengthen the synthesis of compact round
cable core, the gap filling in the cable core to prevent water filling material, the cable core extrusion of polyethylene
sheath into cable.
精确控制的光纤余长保证了光缆具有良好的抗拉性能和温度特性松套管材料本身具有良好的耐水解
性能和较高的强度，管内充以特种油膏 , 对光纤提供了关键性保护聚乙烯 （PE ) 护套具有很好的抗紫
外辐射性能良好的抗侧压性和柔软性采用下列措施来确保光缆的防水性能：
单根非金属中心加强芯。
松套管内填充特种防水化合物。
完全缆芯填充。
Precise control of fiber excess length to ensure the cable has good tensile performance and the temperature char
acteristics of the loose sleeve material itself has good resistance to hydrolysis performance and high strength, tube
filled with special cream, the fiber provides key protective polyethylene (PE) sheathed with softness and good anti
UV radiation performance good resistance to pressure the following measures are taken to ensure the cable water
proof performance: Non
single metal center strengthening core.
Special waterproof compound filled with loose tube.
Full cable core filling.
