ABSTRACT:
A device by which the end of an optical cable incorporated in a power cable is maintained fixed relative to an optical reader while the power cable is being wound onto or unwound from a cable winding drum. The device comprises a first roller on which there can be wound a number of turns of said optical cable equal at least to a fraction of the number of turns of power cable wound on said cable winding drum. The free end of said optical cable is locked in front of said optical reader after it has been wound through at least one turn or a portion of a turn on a roller on which there can be wound a number of turns equal at least to the number of turns which can be wound on said first roller. This latter is rotatably driven. At least said second roller is associated with a mobile structure rotating about and in mechanical synchronization with said roller.
