A fiber optic buffer tube containing fiber optic ribbons centrally located within the buffer tube and a gel compound surrounding the fiber optic ribbons. Disposed within the gel compound, between the walls of the buffer tube and the fiber optic ribbons are gel swellable yarns and/or particles. The gel swellable yarns/particles volumetrically expand when in contact with the gel compound causing greater force to hold the gel compound in place, especially when the fiber optic buffer is heated. The gel swellable yarns/particles also provide greater surface area and help to prevent the fiber optic ribbons from coming into contact with the walls of the buffer tube, thereby preventing signal attenuation problems.
