OPTICAL COMMUNICATION CABLE Russian patent published in 2008 - IPC H01B11/22 

FIELD: electricity; physics.

SUBSTANCE: in optical communication cable containing optical fibers in dielectric tubes, central dielectric reinforcing element, hydrophobic filler, dielectric strip, intermediate dielectric envelope and armoured cove, made of dielectric strips, every of which contains load-bearing element of different diameter, metal load-bearing element in centre of every dielectric strip of the largest diameter projects from the outside of communication cable out of dielectric strip of not more ten half of its radius. And both of extreme metal load-bearing element of each dielectric strip out of dielectric strip by not more then half of its radius by cable circumferential.

EFFECT: defeat hazard decrement of personnel and optical communication cable and keeping of high corrosion resistance of external metal armoured coves.
