GYFTC8Y 48 Core SM G652D Outdoor Fiber Optic Cable are placed in a loose tube made of high modulus plastic. The tubes are filled with a water-resistant filling compound. A FRP locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular cable core. After wrapped with the water blocking tape, this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE) sheath to be figure 8 structure. This kind of cable is specifically applied for self-supporting aerial installation.
