水下光缆 海底光缆 深海光缆 浅海光缆的运用

　　

GDYTA33光电混合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。 缆的中心是一根金属加强芯,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，内置电源线然后用双面镀铬涂塑钢带（PSP）纵包后覆以聚乙烯内护套，内护套外一圈钢丝铠装，最后用聚乙烯外护套成缆。

The structure of ELTFOC-GDYTA33 optical hybrid cable is that the single-mode or multi-mode optical fiber is sheathed in a loose tube made of high modulus polyester material, and the tube is filled with waterproof compound. The center of the cable is a metal reinforced core. The loose tube and the filling rope are twisted around the core to form a compact round core. The gap in the core is filled with water blocking filler. The power cord is built in, and then longitudinally wrapped with double-sided chrome coated plastic coated steel strip (PSP), and then covered with polyethylene inner sheath. The outer ring of the inner sheath is steel wire armored. Finally, the cable is formed with polyethylene outer sheath.

产品特性：

1.精确控制光纤的余长保证了光缆具有很好的抗拉性能和温度特性。
2.PBT松套管材料具有良好的耐水解性能，管内充以特种油膏，对光纤进行保护
3.采用采用涂塑钢带防潮层。

Feature：​

1. The precise control of the surplus length of the optical fiber ensures that the optical fiber has good tensile properties and temperature characteristics.
2. The PBT loose tube material has good hydrolysis resistance, and the tube is filled with special grease to protect the optical fiber
3. Apply plastic coated steel strip damp proof layer.
