Abstract

The invention discloses a self-supporting cicada-preventing butterfly cable which comprises an optical cable body. The optical cable body comprises an outer sheath, a communication unit and a reinforcer, and the outer sheath wraps the communication unit and the reinforcer; the communication unit comprises a winding optical fiber ribbon and two symmetrically arranged protection sheets, and the winding optical fiber ribbon is arranged between the two protection sheets; the two sides of the outer sheath are respectively provided with two tearing grooves, and the distance between the two tearing grooves at one side is greater than the width of the protection sheet, thereby solving the problem that the optical fiber attenuation exceeds the standard or the structure of the optical cable is damaged because cicadas are attached to the optical cable. The invention also discloses production equipment for processing the self-supporting cicada-preventing butterfly cable, the protection sheet pay-off rack is additionally arranged, and the extrusion molding die core and the extrusion molding die sleeve of the plastic extruding machine are improved so that the production process of integrated extrusion molding can be completed, the integrated molding of the novel optical cable is realized, and the production efficiency is relatively high.

Description

technical field

[0001] The invention belongs to the technical field of optical fiber and cable, and in particular relates to a self-supporting anti-cicada butterfly cable and production equipment for processing it. Background technique

[0002] As a common access cable at the end of optical network construction, self-supporting butterfly cable is widely used in network projects such as intelligent buildings, digital communities, smart parks, and digital local area network construction. At present, the common self-supporting cable butterfly cable is constrained by the structure and fiber ribbon technology, and the number of fiber cores is small, most of which are 2-8 cores. With the gradual commercialization of conceptual technologies such as 5G, big data, and artificial intelligence, it is difficult to meet the needs of high-density, large-capacity network construction with a small number of cores. In addition, since most of the self-supporting butterfly-shaped design groov...
