A method of reducing mechanical stress inside a fibre optic cable and a device for performing this method.

摘要

a way of reducing the mechanical stress within the optical cable, fiber optic cable (10) is composed of a reinforcement (6) of optical fibres (4) prstencovu011b arranged around the armature (6), and each optical fiber (4) has a primary coat (2) and a secondary casing (3), and j an optical cable (10) affixed to the outer casing (1).an optical cable (10) is externally heated vu00a0kontinuu00e1lnu00edm mode or vu00a0du00e1vkovu00e9m mode, temperature of heating, which is lower than the lowest melting temperature tt material outer shell (1) of an optical cable (10), or the primary casing (2) of optical fibres (4) or secondary hull (3) of optical fibers (4). the time of heating, after which the fiber optic cable (10) heats is bigger than 1 min.the invention is also a device ku00a0realizaci method described vu00a0kontinuu00e1lnu00edm mode or vu00a0du00e1vkovu00e9m scheme.
