Transmission Media in Computer Networks
Major types of guided media included Twisted Pair Cables, Coaxial Cables and Optical Fiber Cables. Offers higher data transmission rates compared to most wireless media.
What types of metallic optical cables are there
Metallic optical cables include armored fiber optic cables, optical ground wires (OPGW), and optical/metallic hybrid cables, each designed for protection, power line integration, or combined communication and power applications.1. Armored Fiber Optic CablesArmored fiber optic cables are reinforced with a metallic layer, typically corrugated steel tape (CST) or steel wire armor (SWA), to provide mechanical protection against crushing, rodent attacks, and environmental stress. They often feature a central loose tube design filled with gel for water blocking and fiber protection. These cables are suitable for direct burial, duct installations, aerial networks, and industrial environments, ensuring reliable data transmission under harsh conditions .2. Optical Ground Wire (OPGW)OPGW cables combine optical fibers with a metallic ground wire used in high-voltage power transmission lines. They serve a dual purpose: lightning protection for the power line and data communication through embedded optical fibers. OPGW is typically deployed on 110kV to 500kV lines and features a metal armor layer that resists electrical corrosion and mechanical stress. It is mainly used in new high-voltage lines due to construction requirements and safety considerations .3. Optical/Metallic Hybrid CablesThese cables integrate both optical fibers and metallic wires for telecommunication and/or power feeding. According to ITU-T L.109, hybrid cables are classified into three types:Type I: Metallic wires for communication onlyType II: Metallic wires for power feeding onlyType III: Metallic wires for both communication and power feeding Hybrid cables are used in distributed antenna systems (DAS), fiber-to-the-antenna (FTTA) applications, and other scenarios requiring simultaneous data and limited power transmission .4. Other Metallic Optical Cable VariantsAdditional metallic optical cables include:Metal self-supporting optical cables (MASS): Designed to support their own weight on power lines.Phase/ground bundled optical cables (ADL): Combine optical fibers with phase or ground wires for power line integration.Ground wire wrapped optical fiber cables (GWWOP): Optical fibers wound around metallic ground wires for economical deployment on power lines .SummaryMetallic optical cables are engineered to provide mechanical protection, environmental resilience, and integration with power systems. The main types include armored fiber optic cables for harsh environments, OPGW for high-voltage power lines, and optical/metallic hybrid cables for combined communication and power applications. Each type is selected based on installation environment, mechanical requirements, and functional needs.
