OPTICAL COMMUNICATION CABLE Russian patent published in 2009 - IPC H01B11/22 

FIELD: electric engineering.

SUBSTANCE: invention relates to the area of electric engineering; it can be used in makeups of optical cables while laying optical fibre communication lines. For the purpose of easy opening of optical core, removal of optical fibres, easy access to any optical fibre, reduction of recovery time in case of optical cable damage and protection from moisture penetration to optical fibres during optical cable repair each polymer tube with optical fibres is made in the form of C-shaped module with polymer load-bearing element located at the central load-bearing element; peaks of each C-shaped module are directed towards inner surface of inner polymer sheath; waterproof ribbons are located on top of peaks of each C-shaped module; ends of ribbons cover C-shaped module and directed to the central load-bearing element. Two cords tearing inner sheath are located symmetrically to each other and divide the sheath in half; thereat two protrusions at external surface of inner polymer sheath mark location of cords tearing inner sheath.

EFFECT: easy opening of optical core, removal of optical fibres, easy access to any optical fibre, reduction of recovery time in case of optical cable damage and protection from moisture penetration to optical fibres during optical cable repair.
