Composition of communication optical cable
The sheath commonly used for optical cables is a semi-hermetic bonded sheath. It consists of double-sided plastic-coated aluminum strips (PAP) or steel strips (PSP) longitudinally
What type of steel wire is used in optical fiber communication cables
Steel Wire Armored (SWA) cables use galvanized steel wires to provide mechanical protection for optical fibers in harsh environments.Overview of Steel Wire ArmoringIn optical fiber communication cables, steel wire armoring (SWA) is commonly used to protect the delicate optical fibers from mechanical stress, crushing, rodent attacks, and environmental hazards such as moisture and soil acidity . The steel wires are typically galvanized to resist corrosion and are placed between the inner sheath and the outer jacket of the cable . This armoring ensures that the cable maintains its optical performance even under direct burial or in industrial outdoor installations .Construction and FunctionA typical SWA fiber optic cable includes:Optical fibers: Single-mode or multi-mode fibers for data transmission.Strength members: Aramid yarns, FRP rods, or metallic wires to provide tensile strength.Steel wire armoring: Layers of galvanized steel wires that absorb external impact and prevent bending or microbending losses.Outer jacket: Made of PE, LSZH, or PVC depending on environmental and fire safety requirements . The steel wire layer acts as a protective barrier, ensuring long-term durability and minimizing maintenance needs in challenging terrains .ApplicationsSWA fiber optic cables are widely used in:Underground installations: Direct burial cables benefit from the crush and rodent resistance of steel wire armoring.Outdoor fiber networks: Provides protection against environmental stressors like soil pressure and moisture.Industrial automation systems: Ensures reliable data transmission in harsh industrial environments .Comparison with Other Armoring TypesCorrugated Steel Tape (STA): Offers radial compression resistance but less tensile strength compared to SWA.Double Armored Cables: Combine tape and wire for specialized applications like submarine or mining cables . In summary, galvanized steel wires in SWA cables are the standard choice for armored optical fiber cables, providing superior mechanical protection while maintaining high-speed, interference-free data transmission .
