产品描述 Description GYTS 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。双面涂塑钢带(PSP)纵包后挤制聚乙烯护套成缆。 The fibers, 250μm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The PSP is longitudinally applied over the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a PE sheath.   ·产品特点 Characteristics · 具有很好的机械性能和温度特性 · Good mechanical and temperature performance · 松套管材料本身具有良好的耐水性能和较高的强度 · High strength looes tube that is hydrolysis resistant · 管内充以特种油膏,对光纤进行了关键性保护 · Special tube filling compound ensure a critical protection of fiber · 特别设计的紧密的光缆结构,有效防止套管回缩 · Specially designed compact structure is good at preventing loose tubes from shrinking · 良好的抗压性和柔软性 · Crush resistance and flexibility · PE护套具有很好的抗紫外辐射性能 · PE sheath protects cable from ultraviolet radiation · 采用下列措施来确保光缆的防水性能: · The following measures are taken to ensure the cable watertight: - 单根钢丝中心加强芯 - Steel wire used as the central strength member - 松套管内填充特种防水化合物 - Loose tube filling compound - 完全缆芯填充 - cable core filling - 双面涂塑钢带(PSP)提高光缆的抗透潮能力 - PSP enhancing moisture-proof ·产品标准 Standards GYTS 光缆符合 YD/T 901-2001 和 IEC 60794-1 标准 GYTS cable complies with Standard YD/T 901-2001as well as IEC 60794-1. ·光学特性 Optical Characteristics   G.652 G.655 50/125μm 62.5/125μm 衰减Attenuation ( 20℃) @850nm ≤3.0 dB/km ≤3.0 dB/km @1300nm ≤1.0 dB/km ≤1.0 dB/km @1310nm ≤0.36 dB/km ≤0.40 dB/km @1550nm ≤0.22 dB/km ≤0.23dB/km 带宽(A级) Bandwidth (Class A) @850nm ≥500 MHz·km ≥200 MHz·km @1300nm ≥1000 MHz·km ≥600 MHz·km 数值孔径Numerical Aperture 0.200±0.015NA 0.275±0.015NA 光缆截止波长Cable Cut-off Wavelength λcc ≤1260nm ≤1480nm ·结构参数 Technical Parameters   光缆型号Cable Type 光纤数Fiber Count 套管数 Tubes 填充绳数Fillers 光缆直径 Cable Diameter mm 光缆重量Cable Weight kg/km 允许拉伸力 Tensile Strength 长期/短期 Long/Short Term N 允许压扁力Crush Resistance 长期/短期 Long/Short Term N/100mm 弯曲半径 Bending Radius 静态/动态 Static /Dynamic mm GYTS-2~6芯 2~6 1 4 10.2 116 600/1500 300/1000 10D/20D GYTS-8~12芯 8~12 2 3 10.2 116 600/1500 300/1000 10D/20D GYTS-14~18芯 14~18 3 2 10.2 116 600/1500 300/1000 10D/20D GYTS-20~24芯 20~24 4 1 10.2 116 600/1500 300/1000 10D/20D GYTS-26~30芯 26~30 5 0 10.2 116 600/1500 300/1000 10D/20D GYTS-32~36芯 32~36 6 0 10.6 129 1000/3000 300/1000 10D/20D GYTS-38~48芯 38~48 4 1 11.2 141 1000/3000 300/1000 10D/20D GYTS-50~60芯 50~60 5 0 11.2 141 1000/3000 300/1000 10D/20D GYTS-62~72芯 62~72 6 0 12.0 159 1000/3000 300/1000 10D/20D GYTS-74~84芯 74~84 7 1 13.6 209 1000/3000 300/1000 10D/20D GYTS-86~96芯 86~96 8 0 13.6 209 1000/3000 300/1000 10D/20D GYTS-98~108芯 98~108 9 1 15.4 232 1000/3000 300/1000 10D/20D GYTS-110~120芯 110~120 10 0 15.4 232 1000/3000 300/1000 10D/20D GYTS-122~132芯 122~132 11 1 17.2 280 1000/3000 300/1000 10D/20D GYTS-134~144芯 134~144 12 0 17.2 280 1000/3000 300/1000 10D/20D 储存、使用温度: -40℃ 至 70℃ Storage/Operating Temperature : -40℃ to 70℃ 付款方式︰ 预付30%,其它款到发货 产品图片 点击图片放大
