Description

Flat data multimedia cable

Technical field.

The invention relates to a flat data multimedia cable intended in particular for structured cabling and communication systems.

BACKGROUND OF THE INVENTION

Known data and multimedia cables are circular, oval (the vast majority of cables) or special shapes. One of the important transmission parameters to be monitored is the crosstalk between the pairs, ie the amount of energy transferred from the other pairs to the measured pairs, measuring all pair combinations. For frequencies above 100 Hz, a cross-shaped plastic segment is usually inserted into the circular cross-section of the cable between pairs to reduce crosstalk to provide a stable spatial dimension of the pairs with respect to each other and to move them apart (greater distance = less crosstalk). At the highest frequencies required by a 10 Gigabit Ethernet network, there is already a crosstalk between the pairs of the cable itself, but also a crosstalk between the pairs of adjacent cables in the bundle. This can be reduced again by increasing the distance between the cables. This problem is solved, for example, by increasing the thickness of the cable sheath or by spiral wrapping the pairs with a plastic segment of circular cross section placed under the cable sheath, etc. All these variants translate into increased manufacturing effort, material quantity and hence cost of the cable.

From the point of view of the known cables mentioned above, the cable bundles can be divided:

- direct installation of cables without protection in the plaster walls

- laying the cables in pipes (pipes) in the wall plaster

- installation in cable rails on the wall - surface mounting

- installation in window sills on the wall - surface mounting

- mounted in window sills fastened to brackets on the wall

- Installation in plastic, sheet metal or wire cable trays above the plasterboard ceiling cladding

- installation in floor gutters in concrete floors - floor distribution

- installation in the raised floor area

The disadvantage of the mentioned route solutions is the high economic demands in the case of the need to change the route, the price of the route is higher than the price of cables stored in the route. In large-scale offices, where the individual workplaces are separated only by a system of light removable partitions or even by the arrangement of furniture, the route changes very often. In these environments, cable routing changes very often, and there is a problem with cable routing depending on the location of the users.

There are objects with environments in which virtually none of the above routes can be used or such a solution is extremely expensive. Such buildings include listed buildings, interiors with flooring and wall cladding with marble, stone, etc. Also in older buildings with a special load-bearing structure there may be a problem with the implementation of routes for current cabling communication systems. In these buildings, the unfavorable price-to-cable ratio deteriorates many times due to a sharp increase in the cost of work and the need to use special materials in the route.

SUMMARY OF THE INVENTION

The drawbacks of the known solutions are overcome by the flat data multimedia cable according to the invention, which consists of at least one conductor section comprising at least two twisted pairs of conductors arranged side by side and supported by a carrier medium. According to a preferred embodiment of the invention, the twisted pairs of conductors in one conductor section are separated from one another by a spacer gap. According to a further preferred embodiment of the invention, the conductor sections are separated from each other by a separation part. From the point of view of cable routing it is advantageous if the twisted pairs of conductors are laid side by side in a plane.

Placing twisted pairs side by side does not impose space constraints on the required distance between pairs in terms of crosstalk, as is the case with the above-mentioned data and multimedia cable constructions. There is no need to add any additional elements to increase the distance between pairs. The proposed cable solution allows its placement not only in all the routes described above, but also in places where it cannot be used for current cables. The flat data multimedia cable can be laid freely on any floor under the carpet and other types of bulk floor coverings. If the required assembly technology is adhered to, it can also be placed under floating floors, linoleum, tiles and other types of fixed floor coverings. The result of this cable arrangement is also a reduction in the manufacturing costs of the cable itself, but in particular a reduction in the costs associated with the construction or rebuilding of cable routes and its location where other data multimedia cables cannot be used.

Examples

The flat data multimedia cable of FIG. 1 is formed with one conductor section 1 in which two twisted TP conductor pairs are supported on a carrier medium 2, e.g. a plastic film. This cable design can be used eg for analog and digital telephone lines.

The flat data multimedia cable of FIG. 2 is formed with a single conductor section 1 in which two twisted TP conductor pairs are supported on a carrier medium 2, e.g. a plastic film, the twisted TP conductor pairs being separated by a spacer gap 3 and this is due to the crosstalk parameter between twisted pairs of TP wires. This cable design can be used eg for Ethernet 10Mbit / s, 100MBit / s Ethernet or analog / digital audio and video networks.

The flat data multimedia cable of FIG. 3 is formed with a single conductor section 1 in which four twisted TP conductor pairs are supported on a carrier medium 2, e.g. a plastic film, the twisted TP conductor pairs being separated by a spacer gap 3 and this is due to the crosstalk parameter between the twisted pairs of TP wires. This cable design can be used eg for Gigabit Ethernet and 10Gigabit Ethernet computer networks.

The flat data multimedia cable of Fig. 4 is formed with three conductor sections

The individual conductor sections 1 are separated from each other by separation sections 4 in which the conductor sections 1 can be separated from one another, for example by tearing or cutting off. Such separated conductor sections 1 with four twisted pairs of TP conductors k can independently continue off the main cable path to the user connection point - data communication socket, as shown in Fig. 6.
