Pronunciation: [kˈə͡ʊks kˈe͡ɪbə͡l] (IPA) 
The word "coax cable" is used to describe a type of cable that is commonly used in communications and television systems. The spelling of "coax" is derived from the word "coaxial," which refers to the design of the cable itself. The proper pronunciation of "coax" is /ˈkoʊ.æks/. The "o" in "coax" is pronounced with a long "o" sound, while the "a" is pronounced with an "æ" sound. The "x" is pronounced with a hard "ks" sound.
Coaxial cable, commonly referred to as coax cable, is a type of electrical cable consisting of a central conductor, a surrounding insulating layer, a metallic shield, and an outer insulating layer. It is primarily used for transmitting high-frequency electrical signals with low loss of amplitude.
The central conductor, usually made of copper or aluminum, carries the electrical signal or data. It is surrounded by a dielectric insulating layer, typically made of plastic or foam, which provides insulation and helps maintain a constant impedance. The metallic shield, made of conductive material such as copper, prevents external interference from distorting the signal by blocking electromagnetic interference (EMI). The outer insulating layer, often made of plastic, protects the cable from physical damage and insulates it from the surroundings.
Coax cables are widely used in telecommunications, cable television systems, computer networks, and video surveillance applications. They provide a reliable transmission medium for carrying various types of signals, including audio, video, and digital data. The design of coaxial cables allows for efficient transmission of radio frequency signals over long distances with minimal signal loss. The shielding property of coaxial cables also makes them suitable for use in environments with high EMI or radio frequency interference (RFI), ensuring a high-quality signal transmission.
In summary, coax cable is a type of electrical cable that consists of a central conductor, insulating and shielding layers, and an outer protective sheath. It is widely used for transmitting high-frequency electrical signals with reduced signal degradation and improved noise immunity.
The word "coax" in "coax cable" is an abbreviation of "coaxial", which comes from the Latin word "coaxium". The Latin word is derived from the Greek word "koaxos", which means "a cry of triumph". The term was originally used to describe the type of cable that consists of two concentric conductors, one inside the other, separated by an insulating layer. This design allows for more efficient transmission of electrical signals, making it a popular choice for transmitting audio, video, and other data signals.
