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。GYFTYcablestructureisthesinglemodeormultimodefiberintothehighmodulusofthepolyestermaterialmadeofloosetube,casingfilledwithantiWatercompound.Thecoreofthecablecoreisanonmetalreinforcedcore(FRP),forsomeofthecorenumberofopticalfibercable,thenonmetaltostrengthenthecoretobeextrudedonalayerofpolyethylene(PE).Loosetube(andfilledrope)aroundthecentertostrengthenthecoreofthecoretostrengthenthesynthesisofcompactroundcablecore,thegapfillinginthecablecoretopreventwaterfillingmaterial,thecablecoreextrusionofpolyethylenesheathintocable.***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。Precisecontroloffiberexcesslengthtoensurethecablehasgoodtensileperformanceandthetemperaturechar­acteristicsoftheloosesleevematerialitselfhasgoodresistancetohydrolysisperformanceandhighstrength,tubefilledwithspecialcream,thefiberprovideskeyprotectivepolyethylene(PE)sheathedwithsoftnessandgoodantiUVradiationperformancegoodresistancetopressurethefollowingmeasuresaretakentoensurethecablewater­proofperformance:Nonsinglemetalcenterstrengtheningcore.Specialwaterproofcompoundfilledwithloosetube.Fullcablecorefilling.光缆型号(以2芯递增）光纤数缆芯单元数松套管内***大光纤数光缆直径光)
