Abstract: Technologies are disclosed herein for a fluidic composition used to fill or flood a cable, methods for manufacturing the compound, and cables using the composition. The fluidic composition includes a first oil, a second oil, fumed silica, and microspheres. Some formulations of the fluidic composition also include one or more antioxidants. The components of the composition may be blended at temperatures ranging from approximately 80 C to approximately 100 C. In one example, the cable is configured for vertical installations.

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.
