Abstract

FIELD: electricity.

SUBSTANCE: there is a communication cable, which comprises the optical fibers in the water blocking filler in the metal tube, round of which there are the current-conducting copper wires, the intermediate polymeric enclosure, made of the high-pressure polyethylene, and the round-wire armour, made of the zinc-coated steel wires, and the outer polymeric enclosure, made of the high-pressure polyethylene. In this cable, within the metal tube, the optical fibers are placed in pairs (1) in the optical module (3), which is enhanced by dint of the non-conducting reinforcing elements (2) and is protected against the damp. The optical fibers total amount is laid around the central non-conducting load-bearing element in the water blocking filler in the copper metal tube, and the round-wire armour is inserted into the water blocking filler between the intermediate and the outer polymeric enclosures.

EFFECT: capability of the self-sufficient feed system and the operational use simplification.

Description

Technical field

The invention relates to the field of electrical engineering and can be used in the construction of optical communication cables in the construction of fiber-optic communication lines (including along riverbeds).

State of the art

The known design of an underwater optical cable (OK) of the POK-400 brand manufactured by ZAO Sevcable Optic with copper conductors for remote power for laying in the seas and oceans. It contains a central polymer tube with freely laid optical fibers (OB), a hydrophobic compound filled with a round copper wire on top of a polymer tube (conductive remote power supply core), a water blocking tape, a copper tape, an intermediate polymer shell made of high density polyethylene, and round-wire armor over a galvanized galvanized shell hydrophobic filler steel wire, the outer polymer sheath of high density polyethylene (E.L. Portnov Optical cables communication and measurement of their installation, p. 189, Fig. 5.29, M .: Hotline Telecom, 2012. 448 pp.).

The disadvantage of this design is that by constructive design, the organization of power supply to intermediate amplifiers only through the "wire-water" system, which harms the ecology of the aquatic environment, the difficulty of access to the exhaust agent when the OK is damaged and its operation.

There are known designs of underwater optical cables for different laying depths, the design of which is designed in such a way that remote power supply is organized only by the “wire-water” system (S.L. Denisov, I.E. Samartsev General Consideration of Underwater Optical Fiber Communication Lines, p. 170-175, Scientific and Technical Journal T-Comm-Telecommunications and Transport, Special Issue of the 3rd Sectoral Scientific Conference Information Technology Technologies 2009, Issue 1, Part 2 June 2009, Media Publishing House, Moscow: 2009.

The closest in technical essence is the design of the underwater OK (the article by SL Denisov and I.E. Samartsev reviewed above underwater optical fiber communication lines), containing optical fibers in a steel tube, over which copper conductive conductors for remote power supply are laid, copper foil and an intermediate polymer sheath made of high pressure polyethylene, round-wire armor made of galvanized steel wires and an external polymer sheath.

The disadvantage of this design is the design of the remote power circuit, designed to organize the power supply through the "wire-water" system, which harms the ecology of the aquatic environment, the difficulty of repairing the optical cable and optical amplifiers built into the design of the optical cable.

SUMMARY OF THE INVENTION

The task this technical solution is aimed at is the creation of such an optical communication cable design that will allow not only easily organizing the power system autonomously without harming the ecology of the aquatic environment, open the optical core and remove one of the two-fiber optical modules, but also reduce the time repair damage to the OK and protect against moisture penetration all OV during OK repair.

To solve the problem in an optical communication cable containing optical fibers in a hydrophobic filler in a metal tube, around which an intermediate polymer sheath of high pressure polyethylene is laid, and round-wire armor of galvanized steel wires, and an external polymer sheath of high pressure polyethylene, inside the metal tube optical fibers are placed in pairs in an optical module strengthened by means of reinforcing elements and protected from moisture, the total number of which is distributed laid around a central dielectric power element in a hydrophobic filler in a copper metal tube, which will allow not only easy to organize the power system autonomously, without harming the ecology of the aquatic environment, open the optical core and remove one of the two-fiber optical modules, but also reduce the damage repair time to OK and protect all OM from moisture penetration during OK repair.

List of figures

In FIG. 1 shows the design of a river optical cable. It contains a pair of optical fibers 1 with two polymer reinforcing elements 2 in a reinforced and waterproof module 3, the total number of modules is located around the central power element 4 in the hydrophobic filler 5 in the metal tube 6, the intermediate polymer shell 7, round-wire armor 8 in the hydrophobic filler 9 and outer polymer shell 10.

The implementation of the invention

In this design, due to the fact that the optical fibers inside the metal tube are placed in pairs in an optical module strengthened by means of dielectric reinforcing elements and protected from moisture, the total number of which is located around the central dielectric power element in a hydrophobic filler in a copper metal tube, and the round-wire armor placed between the intermediate and external polymer shells in a hydrophobic aggregate, the protection of the river cable from moisture penetration increases .
