Abstract
The utility model discloses an 8-shaped self-supporting type aerial optical fiber. The 8-shaped self-supporting type aerial optical fiber includes a cable core (1) and a protective casing-A (2) wrapping the cable core (1), wherein the cable core (1) comprises a reinforcement member (3) and optical fiber units (4) surrounding the reinforcement member (3); the outside of the protective casing-A (2) is fixedly provided with a protective casing-B (7); the protective casing-A (2) and the protective casing-B (7) are connected through a connecting rib (11); further, the protective casing-A (2), the protective casing-B (7) and the connecting rib (11) are an integrated structure; and suspension wires (8) are disposed inside the protective casing-B (7). According to the 8-shaped self-supporting type aerial optical fiber, a parallel protective casing in which metal reinforcing suspension wires are disposed is added, and thus even if the volume of the optical cable is relatively small, the optical cable has good tensile property and flexibility, can be used both indoors and outdoors. As a result, when the optical cable is connected into an indoor place from an outdoor place, a process of adapter coupling is omitted, working processes are reduced, and time is saved.
Description
Technical field
The utility model relates to a kind of 8-shaped self-support aerial cable.
Background technology
Optical cable mainly is by light transmitting fiber (thin glass fiber such as hair) and plastic protective sleeve pipe and plastic peel formation.Optical cable is the main delivery means of the various Information Networks of current information society.
When existing optical cable was indoor from outdoor access, because the optical cable that indoor and outdoors uses is different, outdoor employing external diameter was thick, pull resistance good, and indoor employing external diameter is thin, flexibility is good, and all namely need to transfer, and require a great deal of time like this.
The utility model content
The purpose of this utility model namely is to overcome the deficiency of present technology, and a kind of 8-shaped self-support aerial cable is provided, and solves existing optical cable and transfers from the indoor needs of outdoor access, the shortcoming of waste plenty of time.
The utility model is achieved through the following technical solutions: the font self-support aerial cable, the sheath A that comprises cable core and parcel cable core, described cable core comprises reinforcement and the fiber unit that arranges around reinforcement, the quantity of described fiber unit is 6, fiber unit comprises the loose sleeve pipe of optical fiber and parcel optical fiber, the outside of described sheath A also is fixedly installed sheath B, sheath A is connected by dowel with sheath B, and sheath A, sheath B and dowel are integrated, and are provided with messenger wire in the sheath B.
Be provided with steel band between described cable core and the sheath A.
Be provided with waterstop between described cable core and the steel band.
Be filled with greasy for preventing water in the slit in the described cable core.
Also be filled with greasy for preventing water in the described loose sleeve pipe.
The beneficial effects of the utility model are: set up a parallel sheath, metal is set in this sheath strengthens messenger wire, namely so that the small volume of optical cable, have simultaneously good pull resistance and flexibility, can be used in indoor and outdoors, when optical cable is indoor from outdoor access like this, namely omit the process of switching, reduce operation, saved the time.
