What is a Coaxial Cable?
Definition and Brief History of Coaxial Cables
Coaxial cables, or coax, as they are commonly known, are a type of transmission line that conveys electrical signals from one point to another. They were first invented in the 19th century, originally designed for the telephone and telegraph transmissions, and later adapted for transmitting television signals, and eventually internet data. The ‘coaxial’ refers to the multiple layers of the cable that share a common axis.
How Coaxial Cables Work for Internet Connection
Coax cables work by transmitting data as electrical signals over a copper core. This core is enclosed in an insulating layer, a conductive shield, and an outer layer for protection. The central core carries the signal, while the outer shield reduces electromagnetic interference, ensuring a clear and stable connection.
When it comes to the Internet, coax cables come into play as a medium to transfer data between your home and your Internet Service Provider (ISP). They are commonly used in broadband internet services offered by cable operators. The coax cable is linked to a modem, which decodes the signal into a digital format that your devices can understand.
Do You Need Coax Cable for Internet?
