Abstract
A cable fill composition for an optical fiber cable, said cable fill composition comprising (i) a Fischer-Tropsch derived base oil; and (ii) a thickening system, wherein the thickening system comprises at least one block copolymer. The cable fill composition of the present invention provides improvements in rheological characteristics, low temperature properties, and colour stability properties, as well as minimizing the levels of additives such as antioxidants and pour point depressants which need to be used.
