GYTS光缆的结构是把250μm光纤套进用高等阻水材料制成的松套管中，松套管内填充阻水化合材料。缆芯的中心是一根金属加强芯，对于多芯光缆来说加强芯需外加一层PE外套。松套管和填充绳围绕中心加强芯互绞紧凑成圆形的缆芯。缆芯内的缝隙充加阻水填充物。双面皱纹钢带（PSP）纵包后挤制聚乙烯护套成缆。。
The structure of GYTS cable is loose sleeve made of 250μm fiber sets into higher water resistance material, loose casing filled with water blocking material.The core of the cable core is a metal reinforcing core. For the multi core cable, a PE coat is required to strengthen the core.The loose sleeve and the filling rope around the core core are twisted into a circular cable core.The crevice in the cable core is filled with water blocking filler.The double sided wrinkled steel strip (PSP) is squeezed into a polythene sheath.
单根钢丝中心加强芯。
The core of the single steel wire is strengthened.
特别设计的紧密的光缆结构，有效防止套管回缩。
Specially designed compact optical cable structure to effectively prevent casing retraction.
采用“SZ”双向层绞技术。
Using "SZ" double direction layer stranding technology.
逐道工序阻水油膏填充。
Filled with water resistance ointment by way of process.
强度高，扭转不开裂。
The strength is high and the torsion does not crack.
光纤余长控制稳定。
The control of optical fiber surplus length is stable.
成缆后，光纤的附加衰减近乎于零，色散值无变化。
After the cable is formed, the additional attenuation of the fiber is almost zero, and the dispersion value is not changed.
全面阻水、双面涂塑钢带-聚乙烯搭边粘结护套，防潮性能优良，具有一定防弹能力。
Comprehensive water resistance, double coated strip - Polyethylene edge bonded sheath, moisture-proof performance, has a certain ability of plates.
