Advantage of guided media
Answers
Answer:
what is guided media.....
Answer:
Advantages:
1.Higher bandwidth
2.Immunity to electromagnetic interference
3.Resistance to corrosive materials
4.Lightweight
5.Less signal attenuation.
Guided transmission media are more commonly known as the wired communication or bounded transmission media. The electromagnetic signals travel between the communicating devices through a physical medium/conductor. As the medium for transmission is a physical conductor, it also provides direction to the signal. But there are physical limitations of the conductor in the guided media. Like the length of the conductor, its installation cost, its maintenance, etc.
The twisted pair cable has two conductors wires wounded around each other and each surrounded by an insulating material.
he coaxial cable has a central core conductor (usually copper) enclosed in an insulating sheath, which is further encased in an outer metallic braid, it serves as both protection against noise and as a second conductor which completes the circuit.
The optical fibre which is made of glass or plastic, and it transmits signals in the form of light. The optical fibre is noise resistance, has less signal attenuation and has a higher bandwidth in comparison to twisted pair cable and coaxial cable.
