A cable assembly is provided, adapted to be installed into a duct by means of a combination of blowing and mechanical feeding. The cable assembly comprises: at least one flexible signal transmitting member for transmitting optical signals, a first layer surrounding said at least one signal transmitting member such that at least one signal transmitting member is in touching contact with said first layer, and a second layer arranged outwardly of said first layer, said second layer being a non-thermoplastic layer comprising a non-thermoplastic, crosslinked polyethylene material. A method of producing the cable assembly is also disclosed.

Polymer blends, films, and coated substrates that include the polymer blends. The polymer blends include at least 90% by weight low density polyethylene polymer and from 1 to 10% by weight ionomer. The LDPE polymer has a melt index (I.sub.2)from 2 g/10 mins to 6 g/10 mins, and a molecular weight distribution from 5 to 11 as determined by a conventional gel permeation chromatography method. The ionomer includes an ethylene acid copolymer, in which from 15% to 70% of acid groups are neutralized by sodium cation based on the total number of acid groups in the acid copolymer. The ethylene acid copolymer is the polymerized reaction product of: at least 50% by wt. ethylene, from 2 wt. % to 40 wt. % of monocarboxylic acid monomer, and from 0 to 20 wt. % of alkyl acrylate, based on the total wt. % of the monomers present in the ethylene acid copolymer.
