● Diameter of the cable is small with a low additional load to the pole and tower.

● Design of stainless steel tube is reasonable and excess lengths of the fiber is correct.

● Stainless steel tube protects the fiber with powerful tensile strength.

● Optical unit of the stainless steel tube is the interlayer of the cable and it can resist twist and has good lateral pressure performance.

● With good safety performance and strong shooting resistance performance, not easy to be stolen

● Different armor combinations or meeting different combinations of electrical and mechanical property.
