Embodiment Construction
[0027] The multi-core bundled self-supporting optical cable and its manufacturing method of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Such as figure 1 As shown, the multi-core bundled self-supporting optical cable and the manufacturing method thereof of the present invention include a suspension wire part and an optical cable part, and the suspension wire part and the optical cable part are connected by suspenders; the optical cable part is composed of a cable core plus two torn The rope 4 is composed of an extruded low-smoke, halogen-free, flame-retardant sheath 7.
[0029] The cable core 8 is composed of a plurality of loose tubes 1 and aramid yarns 2 placed in parallel. The arrangement of the aramid yarn can wrap the loose tube to prevent the loose tube 1 from sticking to the outer low-smoke, halogen-free, flame-retardant sheathing material.
[0030] Compared with the traditional process, the cabling proc...
