Outdoor 1, 2, and 4 core fiber optic single core G657A1 FTTH fiber optic cable. The optical fiber unit is positioned in the center with two parallel FRP or steel wires placed at the sides. Steel wire or FRP serves as additional strength members, and the cable is completed with a black or color LSZH sheath.
