In the GYTS cable, single mode/multimode fibers are positioned in the loose tubes, the tubes are filled with water blocking filling compound. Tubes and fillers are stranded around the strength member into a circular cable core. An PSP is applier around the core. Which is filled with the filling compound to protect it. Then the cable is completed with a PE sheath.

Feature:
1.Good performance under mechanical stress.
2.Loose tube gel-filled construction for superior fiber protection.
3.Longitudinal corrugated steel tape is laminated at both side and bonded to PE outer jacket, it ensures not only radial 4.moisture-proof but also reinforces the crush resistance of fiber optical cable.
5.UV and waterproof design.
