ABSTRACT:
The instant invention relates to a filling composition for optical fiber cable, and a fiber optic cable comprising a protective jacket carrying a fiber optic element therein and the filling composition, in which the filling composition comprises hydrophobic fumed silica; an organic oil; and a thermal oxidative stabilizer, wherein the stabilizer is at most monofunctional with respect to ability to hydrogen bond with the fumed silica. Preferably, the thermal oxidative stabilizer is a hindered phenol and the organic oil, which preferably is a polyalkene oil or a mixture of polyalkene oils, has a viscosity of greater than about 1000 cps at 25.degree. C. The organic oil comprises at least one molecular weight fraction; preferably, the maximum molecular weight for each fraction of the organic oil is less than about 4000 and at least about 80% by weight of the molecules in the organic oil have a minimum molecular weight of about 800.
