The present invention relates to an optical fiber cable comprising a filling material and to the composition of said filling material. In particular, the filling composition according to the present invention comprises an internal polyolefin oligomer to provide an improved capacity for wetting the coating surfaces of the optical fibers which it comes into contact with, and provides better slip of the optical fibers embedded in the composition. The oligomers of the invention comprise internal polyolefins obtained by polymerizing two or more hydrocarbon monomeric units having at least one unsaturation distributed randomly along the whole hydrocarbon chain wherein a mixture of these monomeric units comprises a maximum of 10% of monomeric units having the double bond in the &agr;-position.
