Abstract
An optical cable reinforcement in the form of glass fiber strands �30! having a first coating �32! of a binding agent such as a latex mixture and a second coating �34! of particles �36! of a water blocking agent such as a polyacrylate salt. The particles �36! of water blocking agent are adhered to the glass fiber strands �30! by the binding agent without the binding agent entirely coating the particles of water blocking agent. The unoccluded surface areas of water blocking agent thus provided serve to rapidly absorb/desorb water and protect the optical cable from moisture. A unique powder coating station �60! is used to apply the particles �36! of water blocking agent to glass fiber strands �30! which have been coated with wet binding agent so that the proper adherence of the particles �36! of water blocking agent without complete embodiment, is obtained.
