Description

The claimed technical solution relates to the field of electrical engineering and can be used in the construction of optical cables in the construction of fiber-optic communication lines.

Known optical communication cable No. 2216803 with a priority of 06/04/2002, containing optical fibers in dielectric tubes, a central dielectric reinforcing element, a hydrophobic filler, a dielectric tape, an intermediate dielectric sheath, armor cover and an external dielectric sheath, while the armor cover is made of dielectric tapes, each of which contains power elements of different diameters

The disadvantage of the design of the known cable is that it is not sufficiently protected from moisture and short-lived.

The objective of the proposed technical solution is to increase the period of use of the cable, create additional protection against moisture, increase resistance to tensile forces.

The problem is solved due to the fact that:

Option 1. Optical communication cable, contains a core consisting of a central power element of fiberglass or steel cable, optical fibers in optical modules, or optical fibers in optical modules and cordels, water-blocking aggregate, internal and external dielectric sheaths, water-blocking tape, armor a cover made in the form of a layer of steel wires with galvanic coating or fiberglass rods, a water blocking tape, which is an aluminum tape with a polymer coating, fluoropyridinium polymer layer outside.

Option 2. An optical communication cable, contains a core consisting of a Central power element, optical fibers or optical fibers and

cordels in optical modules, a water blocking filler, inner and outer dielectric shells, a water blocking tape, an armor cover, a layer of threads with a high modulus of elasticity is applied over the core, the armor cover is made of corrugated steel tape, applied longitudinally with overlapping.

Option 3. An optical communication cable containing a core consisting of optical fibers or optical fibers and cordels in optical modules, a water blocking filler, internal and external dielectric shells, a water blocking tape, an armor cover, armor in the form of a layer is applied over the inner shell or over the core galvanized steel wires or fiberglass rods, while under the armor in the form of a coil of steel wires and on top of it is laid a water blocking tape or hydrophobic filler and endorsement tape.

The inventive optical cable is presented in figure 1, figure 2, figure 3.

Figure 1 Optical communication cable, option 1

Figure 2 Optical communication cable, option 2

Figure 3 optical communication cable, option 3

The optical communication cable (FIG. 1), (FIG. 2) contains a central power element 1, optical fibers 2 in the optical modules 3, corde 4, fastening winding 9, inner sheath 8, water blocking filler 7, water blocking tape 6, stripping cord 11 , marking 12 and the armor cover, in figure 1, Option 1 and Figure 3, Option 3, consisting of galvanized steel wire or fiberglass rods 5 or Figure 2, Option 2 steel corrugated tape 13.

The central power element 1 (FIG. 1 and FIG. 2) is made of a fiberglass rod in or without a plastic sheath or a steel cable in a plastic sheath, optical fibers 2 are twisted around the central power element 1 in the optical modules 3, if necessary, plastic structures are introduced corridors 4, interior space

optical modules 3 and the free space between the twisted cable elements is filled with water blocking filler 7 along the entire length of the cable, for example, a hydrophobic compound. For additional protection against moisture, a water blocking tape and / or polymer-coated aluminum tape 6 are longitudinally laid over the core. In this case, the aluminum strip 6 is laid so that the polymer layer is outside. In cables Option 1 and Option 2, an inner dielectric sheath is laid over the core 8. An aluminum sheath, a bitumen coating, and an intermediate sheath can be applied over the inner sheath. In cables, Option 1 and Option 2, FIG. 1 and FIG. 2 over the inner sheath 8 and in cables Option 3, FIG. 3, an armor cover 5 is applied over the core. In the optical cable, Option 3, the core is a polymer tube 14, which contains from 1 to 48 optical fibers 2. Voids in the form of armored wires or glass rods are filled with a water-blocking aggregate, for example, a hydrophobic compound or a water-blocking tape. The option of filling with a combined aggregate of hydrophobic filling and water-blocking tapes is possible.

The presence of water blocking tape 6 in the design of the inventive optical communication cable provides reliable protection against moisture.

The increase in resistance to tensile forces is ensured by the presence of a layer of threads with a high elastic modulus on top of the core
