Problems solved by technology
With the continuous deepening of the country's "5G commercial" construction, the rise of the digital economy, the vigorous development of rural information network construction, the large-scale deployment of FTTH, the continuous advancement of smart villages, video surveillance, broadband high-definition video and other services, the promotion of digitalization With the advent of the era of large traffic, the original optical fiber resources can no longer meet the needs of large traffic
[0003] One-core and two-core butterfly cables are mainly used for FTTH construction and part of residential lines. With the increase in the number of households, repeated laying of butterfly lead-in cables in the same area is increasing, which increases the cost of laying cables.
In particular, optical cables with a low-core structure of less than 2 cores are used for the introduction of optical cables to the home access section of the community and the optical cables used for access networks in rural areas. With the rapid increase in the number of users, repeated laying of optical cables in the same area increases construction costs

The invention discloses an indoor and outdoor four-core butterfly-shaped optical cable and a technological process thereof, and relates to the field of communication hardware manufacturing. The optical cable provided by the invention comprises an outer sheath, a self-supporting piece, a plurality of reinforcing pieces and an optical fiber ribbon. The optical fiber ribbon is of a ribbon-shaped structure formed by coating an optical fiber bundle with an environment-friendly flexible resin material under the action of an ultraviolet light curing oven, environment-friendly flexible resin and optical fibers are cured to form a high-flatness integrated structure, and the external force resistance of the butterfly cable is enhanced. 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 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 an indoor and outdoor four-core butterfly optical cable and its technological process. 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 continuous deepening of the country's "5G commercial" construction, the rise of the digital economy, the vigorous development of rural information network construction, the large-scale deployment of FTTH, the continuous advancement of smart villages, video surveillance, broadband high-definition video and other services, the promotion of digitalization W...
