GYTA/GYTS 光纜的結(jié)構(gòu)是將單模或多模光纖套入由高模量的聚酯材料做成的松套管中，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)芯絞合成緊湊的圓形纜芯，纜芯內(nèi)的縫隙充以阻水填充物。涂塑鋁帶 (APL) 縱包后擠制聚乙烯護(hù)套成纜。

GYTA/GYTS cable structure is the single mode or multimode fiber into the loose tube made of high modulus polyes-

ter material, the casing filled with waterproof compound. The core of the cable core is a metal core, for some of the
core number of optical cable, the metal to strengthen the core need to squeeze a layer of polyethylene (PE). Loose
tube (and filled rope) around the center to strengthen the core of the core to strengthen the synthesis of compact
circular core cable, the core of the gap filled with water to fill the water filled. Coated aluminium (APL) longitudinal
package with a PE sheath cable.
精確控制的光纖余長保證了光纜具有良好的抗拉性能和溫度特性套管材料本身具有良好的耐水解性能和較高的強(qiáng)度，管內(nèi)充以特種油膏對光纖提供了關(guān)鍵性保護(hù)聚乙嫌 (PE )護(hù)套具有良好的抗紫外輻射性能采用下列措施來確保光纜的防水性能：單根鋼絲中心加強(qiáng)芯;松套管內(nèi)填充特種防水化合物 ; 完全纜芯填充 , 涂塑鋁帶 (APL) 防潮層。
Precise control of fiber excess length to ensure the cable has g
