flexible coaxial cable

A coaxial cable is a type of shielded cable used to transmit communications signals for television, telephone, or computer networks. It features two concentric conductors separated by a dielectric insulator. This design minimizes signal loss and interference.1

Flexible coaxial cable, commonly used for cable television connections and historically for local area networks, has a characteristic impedance between 50 and 92 ohms. However, its high signal attenuation limits its use to distances under one kilometer unless repeaters are employed. While largely replaced by fiber-optic and twisted-pair cables for long-distance and high-speed data transmission, flexible coaxial cable remains a standard for short-distance, medium-bandwidth applications.2
