Abstract

This invention relates to multicore optical cables and allows an increase in the capacity of optical cables. In the core-shaped 4-core core 4 cable, there are round helicoidal holes 5 in which additional fibers 2 are laid through the seams 7. After the fibers 2 are laid into the holes 5 and the grooves 6, the depressions 8 are filled with a polymeric material. 1 nl

WITH

The invention relates to the field of optical fibers, in particular, to multicore optical cables.

The purpose of the invention is to increase the cable capacity.

The drawing shows the cable, the cross section.

The cable contains a central power element 1, optical fibers 2, an external protective sheath 3, Bbdt polymer core 4, in which helicoidal round holes 5 and helix-hollow grooves b, interconnected by seams 7t and helicoidal 8, are made.

Fibers 2 into optical cable in

45 optical fibers are laid, with Helsondal’s holes, holes are connected with helicoidal grooves, and helicoidal cuts are made with the possibility of filling

holes 5 uklada1vam hardware through the seams 7

by compressing the cutouts 8 After laying the JQ with a material similar to the material

The portions 2 of the cutouts 8 are filled with a poly-core.

Claims (1)

dimensional material similar to the material of the core 4. The formula of the invention Optical cable containing optical fibers located in the helical slots of a core polymer core having a central power element and surrounded by an outer protective sheath, characterized in that, in order to increase the capacity of the cable, helical round holes are made in the core in which optical fibers are laid, with the heelshondal holes being connected by willows with helicoidal grooves, and in the core there are helicoidal cuts with the possibility of filling up with
