Abstract

The invention relates to a butterfly-shaped leading-in optical cable for a pipeline and a production process thereof. The production process of the butterfly-shaped leading-in optical cable for the pipeline comprises the following steps: step 1, putting an optical fiber into a cable core processing device for processing, putting the obtained optical fiber into a first extrusion molding die, and extruding a protective sleeve material on the surface of the optical fiber by the first extrusion molding die to form a first protective layer, so as to obtain an optical cable cable core; step 2, putting the optical cable core and the reinforcing element into a second extrusion mold, and extruding a protective sleeve material on the surfaces of the optical cable core and the reinforcing element by the second extrusion mold to form a second protective layer to obtain the butterfly-shaped lead-in optical cable for the pipeline; the problems that an existing butterfly-shaped leading-in optical cable for a pipeline is prone to damage, the protection performance on internal optical fibers is not high, and follow-up maintenance is inconvenient are solved.

Description

technical field [0001] The invention relates to the technical field of cable production, in particular to a butterfly lead-in optical cable for pipelines and a production process thereof. Background technique [0002] Butterfly optical cable is a new type of user access optical cable, named for its cross-sectional shape resembling a butterfly. It plays a unique role in the establishment of intelligent buildings, digital communities, campus networks, local area networks and other networks. [0003] The existing butterfly-shaped lead-in optical cable for the pipeline is easily damaged, and the protection of the internal optical fiber is not strong, resulting in inconvenience for subsequent maintenance. When the optical cable is produced, the processing efficiency of the core is low and the processing quality is poor. [0004] In order to solve the above defects, a technical solution is now provided. Contents of the invention [0005] The object of the present invention is ...
