Coaxial cables are commonly used in telecommunications and networking applications to transmit high-frequency electrical signals with low loss of signal quality over long distances. They are often used as a transmission medium for cable television (CATV) signals, internet connectivity, and other broadband services.
Coaxial cables consist of a central conductor surrounded by a dielectric insulator, which is in turn surrounded by a metallic shield or braid, and finally an outer jacket or sheath. This construction provides excellent shielding from external interference and reduces signal loss due to attenuation or noise. Coaxial cables are also relatively flexible and easy to install, making them a popular choice for many applications.
In addition to telecommunications and networking, coaxial cables are also used in a variety of other applications, including video surveillance, test and measurement equipment, and high-frequency instrumentation.
