Disclosed herein is a composition for coating an optical fiber comprising a free radically curable acrylate and/or a methacrylate functionalized oligomer having a density of less than 1.0 g/cm3; where the acrylate and/or the methacrylate functionalized oligomer has a functionality of 1 or more; a photoinitiator; and optionally a free radically curable acrylate and/or methacrylate diluent monomer that has a density of less than 1.0 g/cm3; where the coating composition is disposed and cured on an optical fiber; where the density of the cured coating is less than 1.0 g/cm3; and where the average functionality of the composition is greater than one.
