层绞式非金属加强芯非铠装光缆（GYFTA）详细介绍·产品描述DescriptionGYFTA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。涂塑铝带（APL）纵包后挤制聚乙烯护套成缆。Thefibers,250μm,arepositionedinaloosetubemadeofahighmodulusplastic.Thetubesarefilledwithawater-resistantfillingcompound.AFiberReinforcedPlastic(FRP)locatesinthecenterofcoreasanon-metallicstrengthmember.Thetubes(andfillers)arestrandedaroundthestrengthmemberintoacompactandcircularcore.AfteranAluminumPolyethyleneLaminate(APL)moisturebarrierisappliedaroundthecablecore,thecableiscompletedwithaPEsheath.·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·Highstrengthloosetubethatishydrolysisresistant·管内充以特种油膏，对光纤进行了关键性保护·Specialtubefillingcompoundensureacriticalprotectionoffiber·特别设计的紧密的光缆结构，有效防止套管回缩·Speciallydesignedcompactstructureisgoodatpreventingloosetubesfromshrinking·PE护套具有很好的抗紫外辐射性能·PEsheathprotectscablefromultravioletradiation·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-涂塑铝带（APL）防潮层-APLmoisturebarrier·产品标准StandardsGYFTA光缆符合YD/T901-2001和IEC60794-1标准GYFTAcablecomplieswithStandardYD/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(A级)Bandwidth(ClassA)@850nm≥500MHz·km≥200MHz·km@1300nm≥1000MHz·km≥600MHz·km数值孔径NumericalAperture0.200±0.015NA0.275±0.015NA光缆截止波长CableCut-offWavelengthλcc≤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/DynamicmmGYFTA-2~6芯2~61511.4108400/1000300/100010D/20DGYFTA-8~12芯8~122411.4108400/1000300/100010D/20DGYFTA-14~18芯14~183311.4108400/1000300/100010D/20DGYFTA-20~24芯20~244211.4108400/1000300/100010D/20DGYFTA-26~30芯26~305111.4108400/1000300/100010D/20DGYFTA-32~36芯32~366011.4108400/1000300/100010D/20DGYFTA-2~12芯2~121512.8134600/1500300/100010D/20DGYFTA-14~24芯14~242412.8134600/1500300/100010D/20DGYFTA-26~36芯26~363312.8134600/1500300/100010D/20DGYFTA-38~48芯38~484212.8134600/1500300/100010D/20DGYFTA-50~60芯50~605112.8134600/1500300/100010D/20DGYFTA-62~72芯62~726012.8134600/1500300/100010D/20DGYFTA-2~6芯2~61712.81401000/3000300/100010D/20DGYFTA-8~12芯8~122612.81401000/3000300/100010D/20DGYFTA-14~18芯14~183512.81401000/3000300/100010D/20DGYFTA-20~24芯20~244412.81401000/3000300/100010D/20DGYFTA-26~30芯26~305312.81401000/3000300/100010D/20DGYFTA-32~36芯32~366212.81401000/3000300/100010D/20DGYFTA-38~42芯38~427112.81401000/3000300/100010D/20DGYFTA-44~48芯44~488012.81401000/3000300/100010D/20DGYFTA-50~60芯50~605314.81761000/3000300/100010D/20DGYFTA-62~72芯62~726214.81761000/3000300/100010D/20DGYFTA-74~84芯74~847114.81761000/3000300/100010D/20DGYFTA-86~96芯86~968014.81761000/3000300/100010D/20DGYFTA-98~108芯98~1089117.12261000/3000300/100010D/20DGYFTA-110~120芯110~12010017.12261000/3000300/100010D/20DGYFTA-122~132芯122~13211119.22791000/3000300/100010D/20DGYFTA-134~144芯134~14412019.22791000/3000300/100010D/20D储存、使用温度:-40℃至+70℃Storage/OperatingTemperature:-40℃to+70℃)
