Multicore bundling self-supporting optical fiber cable and manufacturing method thereof

Abstract

The invention discloses a multicore bundling self-supporting optical fiber cable and a manufacturing method thereof, the multicore bundling self-supporting optical fiber cable structurally comprises asuspension wire part and an optical fiber cable part which are connected through a sling; the optical fiber cable part is formed through extruding and wrapping of a low smoke zero halogen flame-retardant jacket by a cable core and two tearing ropes. According to the optical fiber cable, a plurality of loose tubes are used for accommodating a plurality of optical fibers respectively, the loose tubes perform parallel wiring directly in the jacket process, the cabling process is saved, the production work flow is simplified, the production efficiency is improved, and the plurality of core loosetubes can be laid in a branching manner simultaneously.

Description

technical field [0001] The invention relates to an optical cable, in particular to a multi-core bundled self-supporting optical cable and a manufacturing method thereof. Background technique [0002] A series of policy guidelines and technological evolution have promoted a new round of rapid development of broadband access networks, and the demand for optical cables has also grown rapidly. How to further save construction time and space for optical cables and reduce construction costs is a practical problem encountered by optical fiber and cable manufacturers or construction technicians. [0003] In the process of broadband access network construction, 8-shaped optical cables are widely used in network construction because they can withstand a certain tension. However, at present, most 8-shaped access optical cables are loose-tube layer-twisted, and they need to be cabled through the cable-forming process. Afterwards, the sheath is produced; in addition, although the centra...

[0003] In the process of broadband access network construction, 8-shaped optical cables are widely used in network construction because they can withstand a certain tension. However, at present, most 8-shaped access optical cables are loose-tube layer-twisted, and they need to be cabled through the cable-forming process. Afterwards, the sheath is produced; in addition, although the central tube type 8-shaped optical cable can be directly sheathed without cable formation, the optical fibers in the central tube optical cable are all concentrated in a loose tube, and branch laying cannot be performed.
