1. A composition for filling a cable, which contains at least one optical fibre and which can be used between -50 degrees C and + 80 degrees C, said composition being characterised in that it can be injected at a temperature below 60 degrees C, and in that it is composed of : i) 80 to 95% by weight of at least one lubricant base of a viscosity lower than 6000 mPa.s at -40 degrees C, and ii) 20 to 5% by weight of a gelling product belonging to the group comprising the hydroxysubstituted hydrophobic soaps of saturated higher fatty acids, alone or mixed with soaps of saturated higher fatty acids of alkaline and alkaline-earth metals, Bentone and colloidal silica, and in that its dropping point is higher than 120 degrees C and its cone penetrability is between 250 and 400 tenths of a millimetre at +25 degrees C and between 150 and 250 tenths of a millimetre at -40 degrees C. |
