Abstract
A fiber optic cable includes a buffer tube, a plurality of ribbons of optical fibers extending through the buffer tube and a grease layer disposed between at least one pair of adjacent ribbons. The grease layer includes a base component and a plurality of agglomerates formed filler particles, such as silica particles. The major dimension of the majority of the agglomerates is advantageously less than 100 microns in order to reduce microbending of the optical fibers and the resulting attenuation of the signals propagating along the optical fibers. The fiber optic cable can also include a filling compound that is disposed within the buffer tube and surrounds the optical fibers and that is also formed of a base component and a plurality of agglomerates, the majority of which similarly have a major dimension of less than 100 microns.
