Abstract
An optical fibre cable includes, within a surrounding cover, at least one optical fibre extending longitudinally, and a hydrogen-absorptive material comprising a metal cation and an organic anion, preferably dispersed or dissolved in a water-blocking compound. The hydrogen-absorptive material may be a metal salt, preferably a silver salt, of a carboxylic acid, or else a metal loaded ion exchange resin.
