產(chǎn)品描述 Description GYTS 光纜的結(jié)構(gòu)是將 250μm 光纖套入高模量材料制成的松套管中，松套管內(nèi)填充防水化合物。纜芯的中心是一根金屬加強(qiáng)芯，對于某些芯數(shù)的光纜來說，金屬加強(qiáng)芯外還需擠上一層聚乙烯（PE）。松套管（和填充繩）圍繞中心加強(qiáng)芯絞合成緊湊和圓形的纜芯，纜芯內(nèi)的縫隙充以阻水填充物。雙面涂塑鋼帶（PSP）縱包后擠制聚乙烯護(hù)套成纜。 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. 　 ·產(chǎn)品特點(diǎn) Characteristics · 具有很好的機(jī)械性能和溫度特性 · Good mechanical and temperature performance · 松套管材料本身具有良好的耐水性能和較高的強(qiáng)度 · High strength looes tube that is hydrolysis resistant · 管內(nèi)充以特種油膏，對光纖進(jìn)行了關(guān)鍵性保護(hù) · Special tube filling compound ensure a critical protection of fiber · 特別設(shè)計(jì)的緊密的光纜結(jié)構(gòu)，有效防止套管回縮 · Specially designed compact structure is good at preventing loose tubes from shrinking · 良好的抗壓性和柔軟性 · Crush resistance and flexibility · PE護(hù)套具有很好的抗紫外輻射性能 · PE sheath protects cable from ultraviolet radiation · 采用下列措施來確保光纜的防水性能： · The following measures are taken to ensure the cable watertight: - 單根鋼絲中心加強(qiáng)芯 - Steel wire used as the central strength member - 松套管內(nèi)填充特種防水化合物 - Loose tube filling compound - 完全纜芯填充 - cable core filling - 雙面涂塑鋼帶（PSP）提高光纜的抗透潮能力 - PSP enhancing moisture-proof ·產(chǎn)品標(biāo)準(zhǔn) Standards GYTS 光纜符合 YD/T 901-2001 和 IEC 60794-1 標(biāo)準(zhǔn) GYTS cable complies with Standard YD/T 901-2001as well as IEC 60794-1. ·光學(xué)特性 Optical Characteristics 　 G.652 G.655 50/125μm 62.5/125μm 衰減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 帶寬(A級) Bandwidth (Class A) @850nm ≥500 MHz·km ≥200 MHz·km @1300nm ≥1000 MHz·km ≥600 MHz·km 數(shù)值孔徑Numerical Aperture 0.200±0.015NA 0.275±0.015NA 光纜截止波長Cable Cut-off Wavelength λcc ≤1260nm ≤1480nm ·結(jié)構(gòu)參數(shù) Technical Parameters 　 光纜型號Cable Type 光纖數(shù)Fiber Count 套管數(shù) Tubes 填充繩數(shù)Fillers 光纜直徑 Cable Diameter mm 光纜重量Cable Weight kg/km 允許拉伸力 Tensile Strength 長期/短期 Long/Short Term N 允許壓扁力Crush Resistance 長期/短期 Long/Short Term N/100mm 彎曲半徑 Bending Radius 靜態(tài)/動(dòng)態(tài) 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 儲(chǔ)存、使用溫度: -40℃ 至 70℃ Storage/Operating Temperature : -40℃ to 70℃ 付款方式︰ 預(yù)付30%，其它款到發(fā)貨
