·产品描述DescriptionGYTY53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。缆芯的中心是一根金属加强芯，对于某些芯数的光缆来说，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.Asteelwire,sometimessheathedwithpolyethylene(PE)forcablewithhighfibercount,locatesinthecenterofcoreasametallicstrengthmember.Tubes(andfillers)arestrandedaroundthestrengthmemberintoacompactandcircularcablecore.Thecablecoreisfilledwiththefillingcompoundtoprotectitfromwateringress,overwhichathinPEinnersheathisapplied.AfterthePSPislongitudinallyappliedovertheinnersheath,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-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***GYTY53光缆符合YD/T901-2001和IEC60794-1标准GYTY53cablecomplieswithStandardYD/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/DynamicmmGYTY53-2~6芯2~61513.81881000/30001000/300010D/20DGYTY53-8~12芯8~122413.81881000/30001000/300010D/20DGYTY53-14~18芯14~183313.81881000/30001000/300010D/20DGYTY53-20~24芯20~244213.81881000/30001000/300010D/20DGYTY53-26~30芯26~305113.81881000/30001000/300010D/20DGYTY53-32~36芯32~366013.81881000/30001000/300010D/20DGYTY53-38~48芯38~484114.62061000/30001000/300010D/20DGYTY53-50~60芯50~605014.62061000/30001000/300010D/20DGYTY53-62~72芯62~726015.02151000/30001000/300010D/20DGYTY53-74~84芯74~847116.42541000/30001000/300010D/20DGYTY53-86~96芯86~968016.42541000/30001000/300010D/20DGYTY53-98~108芯98~1089117.82901000/30001000/300010D/20DGYTY53-110~120芯110~12010017.82901000/30001000/300010D/20DGYTY53-122~132芯122~13211119.53401000/30001000/300010D/20DGYTY53-134~144芯134~14412019.53401000/30001000/300010D/20DGYTY53-146~216芯146~21619.53451000/30001000/300010D/20D储存、使用温度:-40℃至+70℃Storage/OperatingTemperature:-40℃to+70℃12)?hrs-12:hrs);clckm=((min=12)?Pm:Am;varstnr=;varns=0123456789;vara=;functiongetFullYear(d){yr=d.getYear();if(yrFri,Jul8,2011)
