Explain the advantages and disadvantages of the following guided mediums – Twisted pair, coaxial cable and fiber optic cables.
Solution
Advantages:
1.Easy to work with and install.
2.flexible and light weight.
3.It is the least expensive media for transmission for short distances.
4.If a portion of a twisted-pair cable is damaged, the entire network is not shut down as it may be the case with coaxial cable.
Disadvantages:
1. Easily pick up noise signals which results in higher error rates when the line length exceeds 100 meters.
2. Being thin in size, it is likely to break easily.
Advantages:
1. lower error rates. because the inner conductor is in a Faraday shield, noise immunity is improved, and coax has a lower error rates and therefore slightly better performance than twisted pair.
2. greater spacing between amplifiers coax\'s cable shielding reduces noise and crosstalk, which means amplifiers can be spaced farther apart than with twisted pair.
Disadvantages:
1. more expensive to install compare to twisted pair cable.
2. the thicker the cable, the more difficult to work with.
Advantages:
1. system performance
2. greatly increased bandwidth and capacity
3. lower signal attenuation (loss)
4. immunity to electrical noise
5. immune to noise (electromagnetic interference and radio frequency interference)
Disadvantages:
1.fiber optic component are expensive
2. fiber optic transmitters and receivers are still relatively expensive compared to electrical interfaces
