In GJYX(F)CH fiber, self-supporting drop cable for network access, the optical unit is located at the center, placed around two parallel nonmetal strength members (FRP or KFRP) or metal strength members. Finally, extrude black or chromatic polyvinyl chloride(PVC) or low-smoke halogen-free material (low-smoke, halogen-free, flame retardant) as its sheath.
