·产品描述DescriptionGYTA光缆的结构是将250μm光纤套入高模量材制成的松套管中，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（PL）纵包后挤制聚乙烯护套成缆。Thefibers,250μm,arepositionedinaloosetubemadeofahighmodulusplastic.Thetubesarefilledwithawater-resistantfillingcompound.Asteelwire,sometimessheathedwithpolyethylene(PE)forcablewithhighfibercount,locatesinthecenterofcoreasametallicstrengthmember.Tubes(andfillers)arestrandedaroundthestrengthmemberintoacompactandcircularcablecore.AnAluminumPolyethyleneLaminate(APL)isappliedaroundthecablecore,whichisfilledwiththefillingcompoundtoprotectitfromwateringress.Then,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·Highstrengthlooestubethatishydrolysisresistant·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·PEsheathprotectscablefromultr***ioletradiation·采用下列措施来确保光缆的防水性能：·Thefollowingmeasuresaretakentoensurethecablewatertight:-单根钢丝中心加强芯-Steelwireusedasthecentralstrengthmember-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Standa***GYTA光缆符合YD/T901-2001和IEC60794-1标准GYTAcablecomplieswithStandardYD/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/DynamicmmGYTA-2~6芯2~6149.790600/1500300/100010D/20DGYTA-8~12芯8~12239.790600/1500300/100010D/20DGYTA-14~18芯14~18329.790600/1500300/100010D/20DGYTA-20~24芯20~24419.790600/1500300/100010D/20DGYTA-26~30芯26~30509.790600/1500300/100010D/20DGYTA-32~36芯32~366010.21041000/3000300/100010D/20DGYTA-38~48芯38~484111.01171000/3000300/100010D/20DGYTA-50~60芯50~605011.01171000/3000300/100010D/20DGYTA-62~72芯62~726011.51261000/3000300/100010D/20DGYTA-74~84芯74~847113.41541000/3000300/100010D/20DGYTA-86~96芯86~968013.41541000/3000300/100010D/20DGYTA-98~108芯98~1089114.81851000/3000300/100010D/20DGYTA-110~120芯110~12010014.81851000/3000300/100010D/20DGYTA-122~132芯122~13211116.92281000/3000300/100010D/20DGYTA-134~144芯134~14412016.92281000/3000300/100010D/20DGYTA-146~216芯146~21616.92331000/3000300/100010D/20D储存、使用温度:-40℃至+70℃Storage/OperatingTemperature:-40℃to+70℃牌子好的光缆，质量好的光缆，信誉好的光缆厂，性价比高的光缆，深圳光缆厂，***的光缆厂，***服务好的光缆，用长飞纤芯的光缆，低烟无卤光缆，矿用光缆，层绞式光缆，中心束管式光缆，非金属光缆，铠装光缆，海底光缆，加强芯光缆，室内光缆，室外光缆，架空光缆，直埋光缆，防水光缆，皮线光缆，光纤***光缆，光电混合缆，光电复合缆，馈电光缆，光缆价格，光缆型号，光缆多少钱一米，光缆施工，光缆熔接，跳线缆，防鼠光缆，铝带铠装光缆，钢带铠装光缆，单模光缆，多模光缆，8字型光缆，自承式光缆，GYXTW光缆，GYTA光缆，GYTS光缆，GYTA53光缆，GYTS53光缆，ADSS光缆，紧套光缆，FTTH光缆，GYTY53光缆，皮线缆，4芯单模光缆价格，12芯光缆价格，48芯光缆)
