Optical fiber cable 24 blinds, OBUC 4*6

24 core SM dry earth fiber optic cable (OBUC) is PBN brand with non-zero dispersion with cores (ITU-G6155). The 24-core fiber optic cable consists of 2 loose tubes made of PBT material, inside each of which there are 6 optical cores and 4 fillers. This category of cables is suitable for direct burial under soil and environments with rodents and for long distances. In the following, the structural features of this type of optical fiber are discussed. All properties are fully compatible with the latest revision of TCI specifications.

PBN OBUC-SM cable is an optical fiber ground cable that can be directly buried underground, this type of cable uses G6152D strands, known in the market as SM, which means non-zero dispersion. This cable is resistant to ultraviolet or UV rays due to the use of black high-density polyethylene (HDPE) and Corgit armor. This cable is used for long distances between cities.
