Meanwhile, the polyurethane acrylic coating has the advantages of strong wear resistance, water resistance, chemical corrosion resistance, good insulation and better curing speed.
The sleeve 3 of the scheme preferably adopts a polypropylene semi-loose semi-tight sleeve, because the optical fiber 1 has small diameter and light weight if no free moving space exists in the tight sleeve, and is easy to peel off, lay and connect, but the larger tensile stress directly influences the attenuation performance of the optical fiber.
The sleeve 3 of the present solution is therefore preferably a polypropylene semi-loose semi-tight sleeve. The optical fiber 1 has a certain free moving space in the loose tube, which is beneficial to reducing the influence of external mechanical stress on the optical fiber.
Because the semi-loose and semi-tight sleeve is acted between the loose sleeve and the tight sleeve, the optical fiber has a certain free moving space in the optical cable, and the attenuation performance of the optical fiber influenced by the tensile stress can be relieved. The polypropylene has good processing performance, small moisture absorption, small density and abundant raw material sources; bending resistance, kinking resistance, damp and hot resistance, easy stripping and low cost.
