Abstract
The present disclosure provides an optical fiber cable. The optical fiber cable includes a central strength member. The central strength member lies substantially along a longitudinal axis of the optical fiber cable. In addition, the optical fiber cable includes a first layer. The first layer includes a plurality of water swellable yarns. Further, the optical fiber cable includes a plurality buffer tubes. Each of the plurality of buffer tubes includes a plurality of optical fiber. Moreover, the optical fiber cable includes a second layer of a pair of binder yarns. Further, the optical fiber cable includes a third layer. The third layer is formed of a plurality of water swellable yarns. The optical fiber cable includes a fourth layer. The fourth layer is a sheath layer.
