层绞式非金属加强芯铠装光缆（GYFTY53）详细介绍·产品描述DescriptionGYFTY53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。Thefibers,250μm,arepositionedinaloosetubemadeofahighmodulusplastic.Thetubesarefilledwithawater-resistantfillingcompound.AFiberReinforcedPlastic(FRP)locatesinthecenterofcoreasanon-metallicstrengthmember.Thetubes(andfillers)arestrandedaroundthestrengthmemberintoacompactandcircularcore.Thenthecablecoreiscoveredwithathinpolyethylene(PE)innersheath,whichisfilledwithjellytoprotectitfromwateringress.Alayerofwater-blockingmaterialisappliedaroundthecablecoretopreventwateringressallthesame.Afteracorrugatedsteeltapearmorisapplied.thecableiscompletedwithaPEoutersheath.·产品特点Characteristics·具有很好的机械性能和温度特性·Goodmechanicalandtemperatureperformance·松套管材料本身具有良好的耐水性能和较高的强度·Highstrengthlooestubethatishydrolysisresistant·管内充以特种油膏，对光纤进行了关键性保护·Specialtubefillingcompoundensureacriticalprotectionoffiber·良好的抗压性和柔软性·Crushresistanceandflexibility·采用下列措施来确保光缆的防水性能：·Thefollowingmeasuresaretakentoensurethecablewatertight:-单根非金属中心加强芯-SingleFiberReinforcedPlasticasthecentralstrengthmember-松套管内填充特种防水化合物-Loosetubefillingcompound-完全缆芯填充-100%cablecorefilling-双面涂塑钢带（PSP）提高光缆的抗透潮能力-PSPenhancingmoisture-proof-良好的阻水材料防止光缆纵向渗水-Water-blockingmaterial·产品标准Standa***GYFTY53光缆符合YD/T901-2001和IEC60794-1标准GYFTY53cablecomplieswithStandardYD/T901-2001aswellasIEC60794-1.·光学特性OpticalCharacteristicsG.652G.65550/125μm62.5/125μm衰减Attenuation(+20℃)@850nm≤3.0dB/km≤3.0dB/km@1300nm≤1.0dB/km≤1.0dB/km@1310nm≤0.36dB/km≤0.40dB/km@1550nm≤0.22dB/km≤0.23dB/km带宽(***)Bandwidth(ClassA)@850nm≥500MHz·km≥200MHz·km@1300nm≥1000MHz·km≥600MHz·km数值孔径NumericalAperture0.200&plu***n;0.015NA0.275&plu***n;0.015NA光缆截止波长CableCut-offW***elengthλcc≤1260nm≤1480nm·结构参数TechnicalParameters光缆型号CableType光纤数FiberCount套管数Tubes填充绳数Fillers光缆直径CableDiametermm光缆重量CableWeightkg/km允许拉伸力TensileStrength长期/短期Long/ShortTermN允许压扁力CrushResistance长期/短期Long/ShortTermN/100mm弯曲半径BendingRadius静态/动态Static/DynamicmmGYFTY53-2~6芯2~61715.82301000/30001000/300010D/20DGYFTY53-8~12芯8~122615.82301000/30001000/300010D/20DGYFTY53-14~18芯14~183515.82301000/30001000/300010D/20DGYFTY53-20~24芯20~244415.82301000/30001000/300010D/20DGYFTY53-26~30芯26~305315.82301000/30001000/300010D/20DGYFTY53-32~36芯32~366215.82301000/30001000/300010D/20DGYFTY53-38~42芯38~427115.82301000/30001000/300010D/20DGYFTY53-44~48芯44~488015.82301000/30001000/300010D/20DGYFTY53-50~60芯50~605316.82551000/30001000/300010D/20DGYFTY53-62~72芯62~726216.82551000/30001000/300010D/20DGYFTY53-74~84芯74~847116.82551000/30001000/300010D/20DGYFTY53-86~96芯86~968016.82551000/30001000/300010D/20DGYFTY53-98~108芯98~1089119.23201000/30001000/300010D/20DGYFTY53-110~120芯110~12010019.23201000/30001000/300010D/20DGYFTY53-122~132芯122~13211121.23801000/30001000/300010D/20DGYFTY53-134~144芯134~14412021.23801000/30001000/300010D/20D储存、使用温度:-40℃至+70℃Storage/OperatingTemperature:-40℃to+70℃)
