Optical fibre cables

An optical fibre cable including, within a surrounding cover, at least one optical fibre extending longitudinally, and a hydrogen-absorptive material in which the active part consists solely of a metallic cation and an organic anion, said hydrogen-absorptive material being a metal salt of a carboxylic acid.

An optical fibre cable including, within a surrounding cover, at least one optical fibre extending longitudinally, and a hydrogen-absorptive material in which the active part consists solely of a metallic cation and an organic anion, said hydrogen-absorptive material being an ion exchange resin on which a metal is absorbed.

An optical fibre cable including, within a surrounding cover, at least one optical fibre extending longitudinally, and a hydrogen-absorptive material in which the active part consists solely of a metallic cation and an organic anion which is not obtained by the polymerization of conjugated diene-monomers.

An optical fibre cable including, within a surrounding cover, at least one optical fibre extending longitudinally, and a water-blocking compound comprised of petroleum jelly in or on which a hydrogen-absorptive material comprised of a silver-loaded cationic ion exchange resin is dissolved or absorbed, said jelly and resin forming a mixture of 100 parts jelly to 0.1 part resin.

An optical fibre cable including, within a surrounding cover, at least one optical fibre extending longitudinally, and a water-blocking compound comprised of petroleum jelly in or on which a hydrogen-absorptive material comprised of silver hexanoate is dissolved or absorbed, said jelly and silver hexanoate forming a mixture of 100 parts ajelly to 0.1 part silver hexanoate.

An optical fibre cable including, within a surrounding cover, at least one optical fibre extending longitudinally, and a water-blocking compound comprised of petroleum jelly in or on which a hydrogen-absorptive material comprised of cupric 2-ethyl-hexanoate forming a mixture of 100 parts jelly to 0.2 part cupric 2-ethyl-hexanoate.

An optical fibre cable including, within a surrounding cover, at least one optical fibre extemdomg logintidinally, and a water-blocking compound comprised of hydrocarbon oil in or on which a hydrogen-absorptive material comprised of silver polyacrylate is dissolved or absorbed, said oil and silver polyacrylate forming a mixture of 100 parts oil to 0.1 part silver polyacrylate.
