Cáp quang bọc thép ngoài trời bọc thép lỏng lẻo GYTY53

Các sợi, 250μm, được định vị trong một ống lỏng làm bằng nhựa có mô đun cao.
The tubes are filled with a water-resistant filling compound. A steel wire,
đôi khi được bọc bằng polyetylen (PE) cho cáp có số lượng sợi cao,
locates in the center of core as a metallic strength member. Tubes (and fillers) are
stranded around the strength member into a compact and circular cable core.
The cable core is filled with the filling compound to protect it from water ingress,
over which a thin PE inner sheath is applied. After the PSP is longitudinally applied
over the inner sheath, the cable is completed with a PE outer sheath.
