ABSTRACT:
Plastic ducts suitable for use alone or as components of telecommunications cables to provide for easy installation of optical fibers by blow-in methods, together with optical cable designs incorporating such ducts, are described. The ducts, most preferably provided as plastic tubes, are characterized by inner sidewall compositions of a modified polyvinyl chloride (PVC)-based compound, the compound consisting at least predominantly of PVC polymer but additionally containing up to about 20% by weight of fluorocarbon polymers compounded directly with the PVC.
