Embodiment 1

[0027] An invisible optical cable for indoor use. Two optical fibers 1 are respectively wrapped in two tight sleeve layers 2. The two tight sleeve layers 2 are connected by a connecting body 3 to form an optical unit. The two optical fiber tight sleeves are connected into one body through the connecting body. When wiring indoors, the consistency of the wiring can be maintained, and it is easy to branch from the connecting body when separation is required. At the same time, the dual-core optical fiber can be used one by one, and the other can be used immediately when one optical fiber is damaged, reducing the maintenance response time and avoiding re-construction.

[0028] Two reinforcing cores 4 are placed parallel and symmetrically on both sides of the optical unit, and a sheath layer 5 is extruded to form a cable. Diagonal separation ports 6 are arranged on both sides of the sheath layer 5 . Optical fiber 1 is a bend-insensitive optical fiber, and its color is natural or whi...

Embodiment 2

[0038] Such as Figure 4 , other structures are the same as in Embodiment 1, the difference is that a kind of invisible optical cable for indoor use also includes suspenders 8 and reinforced suspension wires 7, and the reinforced suspension wires 7 are covered with a sheath layer 5, and the sheath layer 5 is connected to the other side through the suspenders 8. Layers are connected. After the suspension wire is added, the optical fiber cable can be used in the outdoor self-supporting overhead scene.

[0039] When this embodiment is implemented: this structure can be deployed in the air with a small span outdoors, and can be introduced from the outdoors to the indoor or directly into the house, whether it is from the outdoor to the indoor and then from the indoor to the indoor, or directly from the outdoor to the indoor. Indoors, when entering the room, the original parts such as the sheath layer and the reinforcing core need to be removed, and only the optical unit is kept.

Abstract

The invention discloses an indoor invisible optical cable and application thereof and relates to the field of optical cables. The indoor invisible optical cable comprises optical fibers and a sheath layer, wherein two optical fibers are respectively wrapped in two tight sleeve layers, the two tight sleeve layers are connected through a connector to form an optical unit, two reinforcing cores are parallelly and symmetrically arranged on two sides of the optical unit, the sheath layer is extruded to form a cable, and diagonal separation ports are arranged on two sides of the sheath layer. The optical unit adopts the transparent nylon or polyurethane sheath, and the optical fiber adopts the natural color and the white color, so visibility of the optical cable during indoor wiring can be reduced, original decoration is not damaged, and the aesthetic property of the decoration is kept to the maximum extent; the two optical fiber tight sleeves are connected into a whole through the connecting body, so wiring consistency can be kept during indoor wiring, and the optical fiber tight sleeves can be easily branched from the connecting body when the optical fiber tight sleeves need to be separated; one double-core optical fiber can be used and the other double-core optical fiber can be standby, and when one optical fiber is damaged, the other optical fiber can be immediately started, so the maintenance response time is shortened, and re-construction is avoided.

Description

technical field [0001] The invention relates to the field of optical cables, in particular to an indoor invisible optical cable and its application. Background technique [0002] With the popularization of large-scale applications of fiber-to-the-home, the demand for indoor optical cables is also increasing. After solving the problem of the "last mile" of network access to the home, everyone has a better understanding of the wiring method and aesthetics of optical cables indoors. high demands. [0003] At present, in order to solve the problem that the indoor wiring of optical cables affects the appearance, there are two common solutions as follows: figure 1 Invisible optical cables are used directly indoors, Figure II The invisible cable is used as an optical unit to add a strengthening core and a sheath layer to form a butterfly-shaped lead-in optical cable. After entering the home, the sheath and the strengthening core are removed, and the invisible optical unit is wir...
