Introduction
Direct Burial Steel Armored Fiber Optic Cable is widely used in today's society, and the fields involve communication, force, and related transmission technology. Armored cable refers to a rope-like cable formed by twisting several or several groups of conductors, each group of conductors is insulated from each other and often around a center. The whole is wrapped by a highly insulating covering. The direct buried cable is directly buried in the lower cable, so it needs higher strength. http://www.kexincables.com/out....door-fiber-optic-cab
