Capacity-expanding weather-resistant rural home-entry leading-in optical cable

Abstract

The invention discloses a capacity-expanding weather-resistant rural home-entry leading-in optical cable. The optical cable is of an 8-shaped structure. The optical cable comprises a suspension wire part (12), an optical cable part (13) and a suspension tape (4). The suspension wire part (12) comprises a metal self-supporting member (1) and a first outer sheath (2). The optical cable part (13) isoval and comprises a second outer sheath (3), a water blocking tape (5) and a disc cable (11), the disc cable (11) comprises an inner sheath (6), an optical fiber tape (7), a first reinforcing piece (8) and a second reinforcing piece (9), the optical fiber tape (7) is arranged in the middle of the inner sheath (6), and four optical cable cores (10) connected side by side are arranged in the optical fiber tape. The beneficial effects of the optical cable are that the optical fiber capacity can be increased, the large-span introduction of the optical cable can be realized, and the performance ofthe introduced optical cable can be ensured under the rural conditions of severe environment and lack of rods and circuits, thereby providing a reliable broadband network and effectively reducing theconstruction cost of the rural broadband network.

Description

Technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a capacity-expandable, weather-resistant rural household entrance optical cable. Background technique [0002] Broadband network is a key infrastructure for economic and social development in the information age, an important driving force for accelerating the transformation of economic development, and a key element for enhancing national competitiveness. Speeding up the pace of broadband network construction is of great significance to comprehensively improving the country's informatization level. From a nationwide perspective, FTTH is a trend in broadband development. At present, urban coverage has been basically completed, and rural FTTH construction has continued to develop. [0003] However, the rural household fiber optic cable deployment environment faces problems such as large spans, large height differences, and high construction and deployment costs. It ...

AI Technical Summary

Problems solved by technology

[0003] However, the deployment environment of rural household optical cables is faced with problems such as large span spans, large height differences, and high construction and deployment costs. There are high requirements for the tensile strength, environmental resistance and optical fiber capacity of household optical cables.

At present, the fiber capacity of pull-resistant home optical cables is generally 1-2 cores, which is low in capacity. Although the fiber capacity of ordinary 4-core butterfly cables is sufficient, it does not meet the tensile performance of long spans.

Therefore, the application of existing household optical cables to rural household scenarios may cause problems such as high construction costs and poor communication quality of optical cables.
