Abstract

The present disclosure provides an optical fiber cable. The optical fiber cable includes a buffer tube substantially present along a longitudinal axis. Further, the optical fiber cable includes a first layer. The first layer surrounds the buffer tube. Furthermore, the optical fiber cable includes a second layer. The second layer surrounds the first layer. Moreover, the optical fiber cable includes one or more strength members embedded inside the second layer. Further, the buffer tube encloses a plurality of optical fibers. Moreover, each of the plurality of optical fibers is color coded from a set of standard fiber colors and wherein the set of standard fiber colors comprises twelve colors. The first layer and the second layer provide a kink resistance, a crush resistance and flexibility to the optical fiber cable. Each of the one or more strength members is coated with a layer of ethylene acrylic acid.
