An optical fiber cable having improved compatibility with a waterblocking filling composition is provided. In particular, the optical fiber cable has a cable component, wherein an optical fiber can be housed, such as a buffer tube or a slotted core, made of a polyolefinic material having high compatibility with a waterblocking filler disposed therein. The cable component is manufactured by employing a suitable polyolefinic material, polyethylene in particular, having a density in the finished component of at least 0.940 g/ml, preferably of about 0.942 g/ml or higher, up to about, e.g., 0.975. The material preferably has a melt flow index (MFI) at 190 ° C. and 2.16 kg lower than about 3 and a shear sensitivity of the same, a shear sensitivity higher than about 40.
