GYHTY 光纜的結構是將 250μm 光纖套入高模量材料制成的松套管中，松套管內填充防水化合物,。纜芯的中心是一根玻璃纖維增強塑料（FRP）,，松套管（和填充繩）圍繞中心加強芯絞合成緊湊和圓形的纜芯。纜芯的縫隙充以阻水油膏后擠制聚乙烯內護套,，再包上一層芳綸后擠制聚乙烯外護套成纜,。

? 具有很好的機械性能和溫度特性Excellent mechanical and temperature performance.
? 芳綸紗為抗拉元件，具有良好的拉伸強度性能Aramid yarn strength member ensure good performance of tensile strength.
? 具有良好的抗壓性和柔韌性,。Good crush resistance and flexibility.
? 松套管材料本身具有良好的耐水解性能和較高的強度Special tube filling compound ensure a critical protection of fiber and resist the water.
? 使用高模量玻璃纖維增強塑料桿（FRP）作為中心加強件Single FRP as the central strength member to withstand axial loads.
?PE護套具有良好的抗紫外線功能 PE sheath protects cable from ultraviolet radiation.
? **纜芯填充  100% core filling water prevent cable jelly to ensure the cable watertight.
