Coaxial cable or coax cable is an electrical wire which broadcasts radio frequency signals from one end to another. The technology has been there since the initial twenty century, with these wires primarily being used to join satellite antenna facilities to houses and businesses because of their toughness and simplicity of setting up. Coaxial cable is of different types, which differ by gauge and impedance. Gauge refers to the cable’s width and is evaluated by the radio guide measurement or RG number. The more the RG number, the thinner is the central conductor core.
Coaxial cable has a distinctive broad, circle shape owing to its internal insulation layer. Its size makes it appear very unlike to other cable types, for instance, twisted pair or Ethernet cable. Moreover, they are available in a variety of colors including brown, black, and white.
In what way Coaxial Cables perform?
Coaxial cables are a well-liked choice as their protected design enables the centre conductor to convey data fast while being guarded from interference and damage. Coaxial cables are essentially built up of these four diverse layers:
• The outside layer is a plastic coating which guards the interior layers from damage
• A conductor which is typically a copper wire, which video and data travels through
• A mesh made from copper then assists shielding the wire from electromagnetic interference
• Nearby the copper cable is a dielectric plastic insulator
Advantages of coaxial cable
• Easy to install and wire
• Inexpensive
• Easy to expand
• Up to 10Mbps capacity
• Excellent resistance to EMI
• Hard-wearing
Another advantage of this cable is the electromagnetic field carrying the signal exists in the space between the outer and inner conductors. This means coaxial cable can be set up beside metal objects without losing power, unlike other transmission lines types.
