把9/125μm单模光纤或50/125μm、62.5/125μm多模光纤（二氧化硅）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和圆形的缆芯。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 9/125μm or 50/125μm, single-mode fiber 62.5/125μm multimode fiber (silica) made of a higher water blocking material into loose tube and the 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 and round core of the loose and filled rope around the core 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.
