ABSTRACT:
A fiber optic dry tube assembly and a method of manufacturing the same includes at least one optical waveguide and a tube. The tube houses at least a portion of the at least one optical fiber and is formed from a bimodal polymeric material. The tube has an average ovality of about 10 percent or less. In other embodiments, the bimodal polymeric material that forms the tube has a melt index of about 1.0 g/10 minutes or less, a melt strength in the range of about 8 cN to about 35 cN at 190° C,. and/or a polydisperity of about 7 or greater. Additionally, the dry tube assemblies of the present invention can form a portion of a cable.
