Embodiment 1

[0040] combine figure 1 and figure 2 As shown, this embodiment provides a light-duty pipe drop cable, which is mainly used in the home broadband communication system of newly built or old cells; the drop cable includes a butterfly cable subunit, a reinforcement 4, a water blocking layer 5 and an outer protective Layer 6, wherein the butterfly cable sub-unit includes a colored optical fiber 1, a butterfly sheath 3 wrapped in the colored optical fiber 1, and a strength member 2 embedded in the butterfly sheath 3, and the colored optical fiber 1 can be one or two , this embodiment takes two colored optical fibers 1 as an example to form an optical fiber ribbon; in this embodiment, a reinforcement 4 is respectively arranged between the gaps 31 of the butterfly wings on both sides of the butterfly cable subunit, and the reinforcement 4 is in a columnar structure and is connected with The colored optical fibers 1 are arranged side by side, and each reinforcing member 4 is arranged...

Embodiment 2

[0049] combine Figure 1 to Figure 4 As shown, this embodiment provides a manufacturing method of a light-duty duct drop cable, which is used to manufacture the light-duty duct drop cable in Embodiment 1. The manufacturing method at least includes the following steps:

[0050] colored fiber 1;

[0051] To make the butterfly cable unit, use the optical fiber and the strength member 2 to tightly sleeve the low-smoke and halogen-free fuel to form the butterfly cable unit; in this process, when the colored optical fiber 1 is tightly sleeved into the butterfly cable unit, it is necessary to strictly control the colored optical fiber 1 , The pay-off tension of the unit reinforcement 2; use a specific non-adjustable eccentric drawing tube mold to ensure that the optical fiber stripping force value can be stably maintained at 6N-9N;

[0052] A reinforcement 4 made of phosphating steel wire is respectively placed between the gaps 31 of the butterfly wings on both sides of the butterfl...

Abstract

The invention discloses a light pipeline leading-in optical cable and a manufacturing method thereof, and relates to the technical field of optical cable manufacturing, the leading-in optical cable comprises a butterfly cable subunit, a reinforcing piece and a water blocking layer, the butterfly cable subunit comprises an optical fiber, a butterfly sheath wrapping the optical fiber and the reinforcing piece embedded in the butterfly sheath, the butterfly cable subunits are respectively provided with a reinforcing piece between the gaps of the butterfly wings on the two sides; the reinforcing pieces are of a columnar structure, and each reinforcing piece is tangent to the side walls of the corresponding notches on the two sides of the reinforcing piece; the water blocking layer tightly wraps the outer sides of the butterfly cable subunits and the reinforcing parts to form a cable core structure, the cross section of the cable core structure is circular, and the reinforcing parts are tangent to the inner side of the water blocking layer; by implementing the technical scheme, the technical problems that an existing lead-in optical cable is inconvenient to construct and low in tensile strength are solved, the light pipeline lead-in optical cable which is smaller in outer diameter, lighter in weight and excellent in bending resistance is provided, construction is convenient, the tensile strength of the optical cable can be effectively improved, and then the input cost is reduced.

Description

technical field [0001] The invention relates to the technical field of optical cable manufacturing, in particular to a light duct lead-in optical cable and a manufacturing method thereof. Background technique [0002] The communication metropolitan area network has formed a basic transmission network covering cities, counties, and towns after the preliminary engineering construction, and has already taken shape, and the operating cost has gradually decreased; various regions have built a comprehensive service transmission network supporting big data and a metropolitan area data network. And the deployment of a complete urban optical cable network has created good conditions for meeting the needs of backup business access. With the development of the data service market and the increasing number of customers in the broadband integrated service smart community, the construction of the broadband access network in the community is imminent, and the intelligent high-speed informa...
