Abstract
The invention discloses an 8-shaped self-supporting overhead optical cable which comprises a cable core (1) and a sheath A (2) wrapping the cable core (1). The cable core (1) includes a reinforcement member (3) and fiber units (4) arranged around the reinforcement member (3). A sheath B (7) is fixedly disposed outside the sheath A (2) and is connected with the sheath A (2) via a connecting rib (11). The sheath A (2), the sheath B (7) and the connecting rib (11) together form an integrated structure. Messenger wires (8) are disposed inside the sheath B (7). The beneficial effects of the invention are that a parallel sheath is additionally installed and metal reinforcement messenger wires are disposed inside the sheath, such that the optical cable is small in size, exhibits excellent pull resistance and flexibility, and can be used both inside and outside a room; and then when the optical cable is accessed from outside to inside, a switch connection process is saved, procedures are reduced and the time is saved.
Description
Technical field
The present invention relates to a kind of 8-shaped self-support aerial cable.
Background technology
Optical cable is mainly by light transmitting fiber (thin as the glass fiber of 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 is indoor from outdoor access, because the optical cable that indoor and outdoors is used is different, outdoor employing external diameter is thick, pull resistance good, and indoor employing external diameter is thin, flexibility is good, and all needs transfers, and requires a great deal of time like this.
Summary of the invention
Object of the present invention 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 present invention is achieved through the following technical solutions: 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 arranging 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 is also fixedly installed sheath B, sheath A is connected by dowel with sheath B, and sheath A, sheath B and dowel are integrated, and in sheath B, are provided with messenger wire.
Between described cable core and sheath A, be provided with steel band.
Between described cable core and steel band, be provided with waterstop.
In described cable core Nei gap, be filled with greasy for preventing water.
In described loose sleeve pipe, be also filled with greasy for preventing water.
The invention has the beneficial effects as follows: set up a parallel sheath, metal is set in this sheath and strengthens messenger wire, make the small volume of optical cable, there is good pull resistance and flexibility simultaneously, can be used in indoor and outdoors, when optical cable is indoor from outdoor access like this, omit the process of switching, reduce operation, saved the time.
