Problems solved by technology

However, the structural feature of the traditional butterfly cable is that the optical fiber is directly covered with the sheath material, and the sheath material has poor strength and is easily damaged by rodent bites.
Repeated construction and repeated maintenance, these problems have seriously hindered the transformation and construction of optical networks, and the huge investment of funds cannot achieve the intended goal

Abstract

The invention discloses a flexible armored butterfly-shaped optical cable and a manufacturing method, which relate to the field of communication hardware manufacturing. The optical cable provided by the invention comprises a suspension wire, an outer sheath, a plurality of reinforcing members and an armored subunit, wherein the spiral steel belt in the armored subunit wraps an armored protection optical fiber, so that the optical fiber can be prevented from being broken after the outer sheath is damaged by mice and other animals; the outer sheath is of an 8-shaped self-supporting structure, sothat good installation performance is achieved while the tensile capacity is ensured; the optical fiber contained in the optical cable has a large degree of freedom in the armored layer and is basically free from external effects such as extrusion, stretching and the like, so that the optical cable has better transmission performance; the optical cable is simple in structure, safe and reliable.

Description

technical field [0001] The invention relates to the field of communication hardware manufacturing, in particular to a flexible armored butterfly optical cable and a manufacturing method thereof. Background technique [0002] Optical fiber is an abbreviation for optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool; optical cable is manufactured to meet optical, mechanical or environmental performance specifications. A communication cable assembly in which one or more optical fibers are used as the transmission medium and can be used individually or in groups. With the deepening of operators' all-optical network layout and the development of urban and rural areas, the functional requirements for optical cables are increasing, such as: faster construction methods, stronger environmental adaptability, and higher safety performance. Major operators have reported that home optical cables have been severely damaged by rats in both ...
