METHOD OF MAKING FIBRE-OPTIC METALLIC MODULE AND DEVICE TO THIS END Russian patent published in 2009 - IPC H01B11/22 H01B12/08 

FIELD: physics.

SUBSTANCE: method and device are designed for making fibre-optic metallic modules, which are made in form of a flexible steel pipe, in which optical fibres (one or more) are put inside the pipe, and free space is filled with a hydrophobic compound. The said module is made by transferring a wire layer from a ready cable, formation of a hollow pipe and putting optical fibres with hydrophobic compound into the pipe. The core of the ready cable is simultaneously removed. A ready serial cable with preferably 5-8 wires or strands is used. The method is realised using a device based on a single-frame cigar, inside of which there is also a receiver for the core and the hydrophobic unit besides the fibre pay-off. The device has two transfer units, which are fitted at the output and input of the cigar, respectively. Each transfer unit has a transfer socket with two cones - input and output and an inclined channel for guiding the fibres and the core, respectively, as well as two grooves - main and auxiliary.

EFFECT: invention allows for making a flexible optical metallic module with good transfer characteristics and high resistance to mechanical and climatic effects, and which is distinguished by small size and weight.
