GJBFJH fiber, multipurpose breakout cable uses a single fiber cable (Φ900μm tight buffered optical fiber, aramid yarn strength member) as its optical unit. The nonmetal strength member and optical fiber unit are stranded at the central strength member in order to form the cable core. Finally, an extruded buffer layer of PVC, LSZH, Hytrel, TPU, ETFE and other different materials is used as the sheathe.
