Abstract

Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having a first inner surface and a first outer surface. The first inner surface defines a central bore along a longitudinal axis of the optical fiber cable. The optical fiber cable also includes optical fibers disposed within the central bore and a buffer tube surrounding the optical fibers. The buffer tube has a second inner surface and a second outer surface. The optical fiber cable also includes an armor layer disposed between the first inner surface of the cable jacket and the second outer surface of the buffer tube and a water-blocking adhesive disposed between the armor layer and the first outer surface of the buffer tube. The water-blocking adhesive extends along the longitudinal axis of the optical fiber cable and around a circumference of the buffer tube.
