GYTC8A 光缆的结构是将 250μm 光纤套入高模量材料制成的松套管中，松套管内填充防水化合物。缆芯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和圆形的缆芯。缆芯用一层涂塑铝带(APL)纵包后，和钢丝绞线集成到一个8字型的聚乙烯护套内。可提供Y护套或S护套的8字型光缆GYTC8Y、GYTC8S等，此类产品多应用于自承式架空敷设。
The structure of GYTC8A fiber optic cable is to insert a 250μm fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound.he center of the cable core is a metal reinforced core, and the loose tube and filers is twisted around the center reinforced core to form a compact and circular cable core. The cable core is longitudinally wrapped with a layer of APL and integrated with the steel wire strand into a figure & polyethylene sheath.Figure 8 fiber optic cables like GYTC8Y, GYTC8S, etc, with Y or s sheaths, and these products are mostly used for self-supporting aerial laying.
