What is Coaxial cable


Coaxial cable is a kind of copper cable that was constructed specifically for the purpose of blocking signal interference with metal shield and other elements. Cable TV companies mainly utilize it to link customers ' homes and companies with their satellite antenna equipment. Telephone companies sometimes connect central offices to customer-specific telephone poles. Some houses and offices use coaxial cables, too, but the extensive use of coaxial cables as an Ethernet connection device in companies and data centres.

Cable operators, telephone companies, and web providers around the world use coaxial cables to communicate data, video, and voice to clients. It is also widely used within homes.It has been around as a technology for a long time and has numerous unique advantages for reliable, exact transmission.

In 1880 English engineer and mathematician Oliver Heaviside invented the coaxial cable, who had the same year patented the invention and design. In 1940, AT&T established its first coaxial transmission system crosscontinental. Twisted copper wire and optic fiber are alternatives to coaxial cables, depending on the transport technology used and other factors.

Four main parts are included in the coax cable are:

  • The fist layer is of core copper wire that acts as the main channel and carry the data or information.
  • The second layer is of plastic dielectric insulator that surrounds the copper which manage the network traffic.
  • The third part is of copper Mesh or metallic shield which is used to save the signals from collision.
  • The last layer of plastic coating is used to protect the inner layers, such as fire and water, from physical damage.

Coaxial cables are more distant to carry signal and for their layered protection are a good way of choosing low signal. A number of coaxial cables are classified by the diameter of the copper core and number of protective sheaths.

The tight control of cable sizes and materials is a key to coaxial cable design. Together, they guarantee a set value for the distinctive impedance of the cable. In impedance malfunctions, the high frequency signals are partly reflected and cause mistakes.

The feature impedance is susceptible to frequency of signals. The cable manufacturer should use a dielectric system above 1 GHz that does not too much attenuate the signal or alter the feature impedance in a manner that generates signal reflections.

The application-dependent and essential electrical properties of Coaxial are important for excellent performance. There are two normal feature impedances 50 ohms, usual for antenna links and residential facilities, in mild energy settings and 75 Ohms.


Type of coaxial cables

RG-6,RG-11andRG-59 are the three most common type of cable sizes prevalent.

RG-6 coaxial cable

RG means' radio Guide.' Diameter numbers are given to the different variants of RG cable (59 signifying 0.059, 6 meaning 0.06, etc.) They are also called "radio frequency" RF cables.

Most non-industrial coax is known to RG-6, but a thicker wire, as RG-11 can be used by installers.
