Abstract
The invention discloses a self-supporting layer-stranded type optical fiber composite low-voltage optical cable for an access network. The self-supporting layer-stranded type optical fiber composite low-voltage optical cable comprises an optical unit, a conductor and an outer sheath which coats the optical unit and the conductor, wherein a steel wire suspension wire and an outer sheath layer thereof are arranged on one side of the outer sheath; and a suspension belt is arranged between the outer sheath and the outer sheath layer and used for connecting the outer sheath and the outer sheath layer into a whole. The self-supporting layer-stranded type optical fiber composite low-voltage optical cable is low in cost and convenient to install and has a function of transmitting an optical signal and an electric signal at the same time. Meanwhile, the optical unit is a layer-stranded type optical unit which has a loose-sleeve fully-dried type structure; and the interior of a sleeve or a cable core is made of a dried type water blocking material, so that water-proof and moisture-proof effects of total cross-section are achieved.
Description
Technical field
The application relates to a kind of Access Network that has light signal and signal of telecommunication transfer function simultaneously with self-bearing type layer-twisted type Optical Fiber Composite low-voltage optical cable.
Background technology
The present invention is mainly used in the construction of distribution network segment intelligent grid; Optical fiber and low-voltage power line set are lumped together; Adopt the built on stilts mode of laying of self-bearing type directly to get into the user by machine room; Solve machine room to multimedia services such as the power supply between the user, Internet data communication, video request program, video telephone, video conferences, finally realize current collection power transmission network, telecommunications network, Television Broadcasting Network and the Internet target in " four nets merge " of one.
Access Network is compared with traditional Optical Fiber Composite low-voltage cable with the compound low-voltage cable of self-supporting fiber and is had following advantage:
(1) new invention adopts butterfly light unit to be positioned in the whole cable, and the light unit can be separated from cable, makes things convenient for light-electricity to separate, and the equipment of being convenient to light unit and power unit inserts;
(2) new invention adopts butterfly light unit, builds with existing FTTx to be complementary, and is beneficial to quick connector and continues or be connected to miscellaneous equipment, and networking flexibility is convenient;
(3) new invention employing self-bearing type is built on stilts lays, and in rural area or sub-district cable construction, a kind of brand-new access way is provided.
Summary of the invention
The Access Network of designing and developing is directly to be introduced into butterfly light unit in the construction of cable with the main summary of the invention of the compound low-voltage cable of self-supporting fiber; Construction of Optical Fiber Composite cable and FTTx construction at present are complementary; In the construction of distribution network segment intelligent grid, can indiscriminately imitate the advantage that existing FTTx builds; Make the networking flexibility aspect and hang down into cheaply, build the condition that provides for the distribution network segment is intelligent.
Realized the composite rope of following structure: a kind of Access Network is with self-bearing type layer-twisted type Optical Fiber Composite low-voltage optical cable, and this composite rope comprises light unit and conductor and the oversheath that coats them, is provided with steel wire messenger wire and outer jacket thereof in a side of oversheath; Be provided with suspender belt between oversheath and the outer jacket and fuse, said conductor has insulating barrier outward, and said smooth unit is butterfly light unit; This butterfly light unit comprises the optical cable that is positioned at the center, and respectively there is a reinforcement optical cable both sides, and this optical cable is layer-twisted type light unit; This layer-twisted type light unit is followed successively by from outside to inside: light unit sheath, waterstop, loose sleeve pipe; The dry type water-blocking material, optical fiber, water blocking yarn; Non-metal reinforcement member, gasket for packing.
Wherein, above-mentioned insulating layer of conductor, gasket for packing and oversheath adopt fire proofing.
Wherein, fire proofing is PVC or LSZH.
The invention effect:
(1) difficult connection of march-past optical fiber and not segregative problem in the Optical Fiber Composite low-voltage cable have been solved;
(2) quoting of butterfly light unit makes that intelligent grid construction and existing FTTx are built in the power distribution network and is complementary, and solved in the power distribution network communication access net " last 300 meters " as the bottleneck problem of electric network information construction;
(3) for the intelligent grid line construction a kind of new system of laying is provided.
The invention meaning:
Access Network is introduced into butterfly light unit in this invention with the compound low-voltage cable of self-supporting fiber; And consider that present rural area or sub-district cable wiring characteristics, construction cost and construction are difficult to degree; The built on stilts notion of laying of self-bearing type is introduced in success; Make that low pressure stage " last 300 meters " electric network information construction bottleneck problem is able to solve, quickened China's intelligent grid cable construction.
