FIELD: optical instrument engineering. SUBSTANCE: fiber-optic cable has many fibers disposed along the central part. Protection pipe, filled, with gel, has to be carrier element for optic fibers. Many radial strengthening braidings pass along the external side of protection pipe along helix at opposite directions. Strengthening and protecting element may be provided in armored cable, which element is made in form of steel armored layer to provide additional protection against possible damage caused by drivels. Armored coating can be covered by thin layer of plastics, made in form of water-proof compound. Rip cord is provided to help removing of armored coating and external housing to be protected for supplement. Pair of longitudinal strengthening rods is introduced into external housing, which rods are opposed diametrically. EFFECT: improved accuracy. 5 cl, 3 dwg
