GYTA/GYTS 光缆的结构是将单模或多模光纤套入由高模量的聚酯材料做成的松套管中，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的圆形缆芯，缆芯内的缝隙充以阻水填充物。涂塑铝带 (APL) 纵包后挤制聚乙烯护套成缆。
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.
***控制的光纤余长保证了光缆具有良好的抗拉性能和温度特性套管材料本身具有良好的耐水解性能和较高的强度，管内充以特种油膏对光纤提供了关键性保护聚乙嫌 (PE )护套具有良好的抗紫外辐射性能采用下列措施来确保光缆的防水性能：单根钢丝中心加强芯;松套管内填充特种防水化合物 ; 完全缆芯填充 , 涂塑铝带 (APL) 防潮层。
