The structure of the indoor/outdoor dual-purpose interlocking armored fiber optic cable is to place aramid reinforcing elements on the surface of the 0.9mm tight-buffered optical fiber, and then put it into an inner sheath made of PVC/LSZH material. The inner sheath is further covered with an interlocking aluminum armor, and the outermost layer is encased in an LSZH/PVC/PE material outer sheath.
