Abstract: The present invention relates to a sheath (7) for a cable (1), the sheath comprising, at least in part, a halogen-free intumescent composition, said sheath being characterized in that said composition contains a mixture of: a polymer matrix chosen from a polyethylene, a polypropylene, an ethylene copolymer, a propylene copolymer, a silicone, a polyamide, and a mixture thereof; and at least one flame-retardant additive constituted by a first inorganic compound having a lamellar crystal structure, and by a second inorganic compound inserted between the lamellae of said first compound, said second compound being capable of causing said lamellae to move apart under the effect of heat. This sheath is for use as a flame retardant in telecommunications cables.

Abstract: The present invention relates to an optical device comprising an ionic conductor and a pair of electrodes, the ionic conductor being made of a material that is transparent to light and contains mobile ions and the electrodes being suitable for absorbing and desorbing the ions and being in ionic contact with the ionic conductor. The refractive index in at least a zone of the ionic conductor can be varied under the effect of the voltage applied between the electrodes. The electrodes contain an electrochemically active material selected from an active carbon, a conductive polymer, and an insertion material suitable for inserting ions in its structure.
