High-performance soft-type cable-carrier optical cable and manufacturing method of high-performance soft-type cable-carrier optical cable

Abstract

The invention discloses a high-performance soft-type cable-carrier optical cable. A polyurethane protection layer is arranged outside an aramid fiber reinforcing core, a plurality of optical fiber units are contained between the polyurethane protection layer and an inner polyurethane jacket, a polyurethane jacket layer is arranged outside each optical fiber unit, a polyester silk woven layer and an outer polyurethane jacket are sequentially arranged outside the inner polyurethane jacket in a sleeved mode, and each optical fiber unit is sequentially composed of a loose tube, an aramid fiber filling layer and an optical fiber from outside to inside. A manufacturing method of the high-performance soft-type cable-carrier optical cable includes the following steps: rod prefabricating, fiber drawing, secondary coating, optical fiber and aramid fiber stranding, loose tube extruding, cabling, inner jacket extruding, reinforcing layer weaving, outer jacket extruding, finished product inspection, packaging and storing. According to the high-performance soft-type cable-carrier optical cable and the manufacturing method, the reasonable structure is designed, and the reasonable manufacturing process is made, so that the good optical signal transmission performance is guaranteed, the bending performance, the tensile performance and the twisting resistance of the cable can be further guaranteed, and the service life of the cable is prolonged.

Description

technical field [0001] The invention belongs to the field of port machinery, and in particular relates to a high-performance soft tow optical cable and a preparation method thereof. Background technique [0002] The high-performance flexible tow cable is laid outdoors and is often used in harsh environmental conditions, such as: long-term sun and rain, day and night cold, frost and snow, ultraviolet rays, ozone and other natural conditions, and the performance declines relatively quickly. The service life is relatively short. [0003] During the use of high-performance soft tow cable cables, under the condition of ensuring good transmission of optical signals, the cables must withstand tensile force, torsion and bending fatigue, resulting in a rapid decline in the performance of insulation and sheath materials, and the service life of optical signal transmission relatively short. [0004] The high-performance flexible tow cable has relatively high requirements on the sheat...
