Description

The technical field to which the utility model relates.

The utility model relates to cable technology and is intended for simultaneous use in a wire broadcasting network and broadband access network, for laying distribution feeders that combine the ability to transmit three-program wireline broadcasting (TPV) programs to electric power subscribers and high-speed data transmission using fiber-optic technology.

State of the art

Known optical cable (patent RU 78335, publ. 20.11.2008) containing a double outer polymer sheath and a steel optical module, inside of which at least one optical fiber and a hydrophobic filler are placed.

The disadvantage of the technical solution is the impossibility of using it in a wire broadcasting network for broadcasting TPV programs and supplying fiber optic equipment, an insufficient number of optical fibers, as well as the inability to cut through while maintaining the integrity of the power element for suspension.

Known optical cable combined (patent RU 57047, publ. 09/27/2006), which contains optical fibers placed in two tubes in an amount of at least two in each, a conductive core with insulation from polyethylene in a common sheath of thermoplastic material, an additional conductive core in polyethylene insulation, insulated conductive conductors and the mentioned tubes are twisted together and wrapped with aramid thread, and under the shell of the polyethylene composition aramid thread is also longitudinally skipped.

The disadvantage of the technical solution is the insufficient number of optical fibers, the insufficient strength provided by the aramid thread, as well as the inability to cut through while maintaining the integrity of the power element for suspension.

Utility Model Essence

The task to which this technical solution is aimed is to expand the arsenal of means of integrated information delivery.

The technical result consists in the creation of a cable that allows the use of one suspension for the simultaneous transmission of electrical power of TPV programs in a wire broadcasting network and high-speed data transmission using fiber-optic technology over a broadband access network, which is implemented when laying distribution feeders.

The technical result is achieved by the fact that in a combined optoelectric cable including optical fibers located in the module, according to the proposed solution, a copper core for broadcasting TV programs on a wire broadcasting network and a copper core for powering the equipment of a fiber-optic communication line, and a fiberglass bar are additionally introduced as an additional power element, while the intramodular and modular space is filled with a water blocking gel.

Brief Description of the Drawings

The proposed design of the utility model is illustrated in the drawing.

In FIG. 1 shows a general view of an optoelectric combined cable; FIG. 2 cable is shown in section.

Utility Model Implementation

The cable consists of optical module 1 in a sheath of dense polyethylene water-repellent material, with module 2 placed with 16 single-mode optical fibers in a polymer modular tube 3, copper core 4 with a cross section of 1 × 1.5 mm ² - for broadcasting TPV programs over a wired network broadcasting, copper core 5 with a cross-section of 1 × 2.5 mm ² for powering the VOL equipment, an additional power element 6, made in the form of a fiberglass rod with a diameter of 4 mm. Intra-modular and modular spaces are filled with water blocking gel 7.

- connecting the copper core to the cable sheath in the extruder with the corresponding formers;

- cooling the finished cable in the bath;

- verification of parameters, insulation;

- formation of coils.

The characteristics of the claimed cable:

- resistance to tensile load - not less than 15 kN;

- maximum crushing force of at least 1.0 kN / cm;

- the minimum allowable operational bend - 20 diameters of the outer sheath of the cable;

- the range of cable operating temperatures should be: from minus 50 ° С to plus 60 ° С;

- does not spread combustion in the beam (category C);

- non-toxic, does not emit corrosive substances;

- low optical density of smoke during smoldering (burning).
