Abstract:
1. An optical-fiber buffer tube, comprising: an optical fiber comprising (i) a glass fiber and (ii) one or more optical-fiber coating layers surrounding said glass fiber, said one or more optical-fiber coating layers defining an outermost optical-fiber coating layer, wherein said optical fiber's outermost optical-fiber coating layer is a urethane-acrylate composition; a chemically modified polydimethylsiloxane prewetting agent applied to said optical fiber's outermost optical-fiber coating layer, wherein, at standard temperature and pressure of 20° C. and 1 atmosphere, said prewetting agent has an interfacial adhesion with said optical fiber's outermost optical-fiber coating layer of at least about 2.4 dynes/cm a polymeric sheath enclosing (i) said optical fiber and (ii) said prewetting agent applied to said optical fiber's outermost optical-fiber coating layer.
