Bonding is the connection of all metallic components in the cable sheath together (metallic armor and metallic central strength members) to keep them at the same potential and ensure electrical continuity with sufficient capacity to safely conduct any imposed current to. Bonding is the connection of all metallic components in the cable sheath together (metallic armor and metallic central strength members) to keep them at the same potential and ensure electrical continuity with sufficient capacity to safely conduct any imposed current to. Bonding is the connection of all metallic components in the cable sheath together (metallic armor and metallic central strength members) to keep them at the same potential and ensure electrical continuity with sufficient capacity to safely conduct any imposed current to ground. Grounding is defined. Research conducted by the US Department of Agriculture, Rural Utilities Service (RUS), (formerly known as the Rural Electrification Administration) has demonstrated the outstanding resistance of copolymer coated steels to corrosion. However, when optical fiber cable contains metallic components such as steel armor or strength members, it is necessary to ground and bond the fiber optic cable to reduce radiated and conducted. An armored optical cable is a special optical cable with a protective stainless steel armor tube wrapped around the fiber core. The metal armor layer effectively protects the fiber core from animal biting, moisture corrosion and various external damages. While retaining the transmission performance. Metallic elements include armor, steel strength members, and toning wire.
