Coaxial cable is in common use by telephone companies, cable operators and global internet providers in order to send data, voice and video communications to their customers, and is also in extensive use in everyday households.
The coaxial cable has been in use for a very long time at this point, having been around since early last century and comes with a number of inherent advantages in regards to sending transmissions that are accurate and reliable.
The patent for the coaxial cable was filed in 1929 and granted in 1931. They are used for the efficient transportation of high frequency signals, making them ideal for broadband applications in the 21st century as well as for use as a link between devices and satellites, which also makes them very effective and efficient for TV signals.
The key to the success of the coaxial cable is its shielded design, which enables the copper core of the cable to be able to transmit data very quickly without suffering damage or interference due to environmental factors.
That design also means that they are incredibly durable, protecting the interior conductors that all share a single axis, which is where the name “coaxial” comes from.
Cable sizes and styles
RG-6, RG-11 and RG-59 are the most common sizes for coaxial cables. RG means “Radio guide”, with the numbers of the various versions of RG cables referring to the diameter. They are also often referred to as RF cables, with RF standing for “Radio frequency”.
RG-6 is used in the majority of non-industrial cables, but installers may use RG-11 as it is a thicker cable. The Hybrid-Fibre Coaxial is an evolution of this type, offering superior performance due to its considerably higher gauge.
A Hard-Line Coaxial Cable (HFC) is a system that runs fibre optic cables to a node and uses coaxial cables to split them to different households.
A Triaxial cable makes use of cables manufactured from solid copper, offering superior screening at higher frequencies and being even more durable than the norm.
The majority of connectors are F-style, but some systems may use of N-Style connectors. These connectors come in several styles for RG-6 cables, including compression connectors, crimp-style connectors and screw-on connectors.
Male and female connectors of the same type are required to make a connection.
What are the most common uses of a coaxial cable?
Coaxial cables are frequently made use of as transmission lines for the likes of data and video signals and radio frequency.
They have often been utilised as feed lines for the connecting of radio receivers and transmitters with antennas, cable television and digital audio signals and internet connection.
They are also very popular in LANs (Local Area Networks) in industrial settings due to the shielding making them resistant to interference from other devices.
Businesses are more reliant than ever on the internet for both internal and external operations, from the shipping of big orders to reaching out to clients, and coaxial cable internet has become a hugely popular business access solution as a result.
Coaxial cables have a number of advantages over other forms of transmission lines, working at extremely high frequencies and often still capable of being used even with poor attenuation. In some cases particular coaxial cables even have the ability to remove distorted signal transmission.
