GYTS cable is universal optical cable; it can be used in aerial, duct and direct-buried while GYTA can be used in aerial cable and duct cable not in direct-buried cable.The S in GYTS refers to steel strip which can sustain large pulling force, theA in GYTA refers to Aluminum strip which has better anti-rust and moisture resistance than steel strip,. PBT loose tube of 2-12 fiber, Tube thickness: 0.3±0.05mm, Diameter: 2.1±0.1um, Fiber (Fiber characteristic), Cladding diameter: 125.0±0, Fiber characteristics: Diameter: 242±7 um, UV color fiber: Standard chromatogram. Central Strength member: steel wire with Diameter: 1.6mm. It has a Filling Compound; Longitudinal corrugated steel tape laminated w. 1-Up to 144 fiber cores. 2-The loose tube stranding technology make the fibers have good secondary excess length and allow 3-The fibers free movement in the tube, which keeps the fiber stress-free while the cable is subjected to longitudinal stress. 4-Corrugated steel tape armored and PE outer sheath providing property crush resistance and gun shot.
