Question

Select the correct statement(s) regarding UTP.

a. UTP signals are balanced, meaning that one wire transmits the signal, while the other wire is connected to ground

b. All UTP wire pairs within a cable (e.g., Cat 5e) are twisted at exactly the same twist ratio

c. UTP signals are balance, which means that each wire within a pair carries the same signal, but with opposite polarities

d. Crosstalk is never a problem with UTP

Coaxial conductors use unbalanced signals, which means that it is less capable than UTP balanced conductors with regards to data rate capacity and attenuation.

True or False

Explanation / Answer

Option c is the only correct statement about UTP.

Option a is not correct because, if one wire transmit signal and other connected to ground, then signals are unbalanced . But UTP has balanced signals.

Option b is not correct, as all the pairs are twisted at different rate, in order to reduce the interference effect in UTP.

Option c is correct as UTP has balanced signals, where both the wires transmits the same data, with one positive and other negative. Therefore if equal noise occurs in both lines , it can get cancelled.

Option d is also not correct as crosstalk can occur in UTP. Because the each twisted pairs in UTP are not shielded from each other. If a wire in one pair is parallel to another wire in another pair, one can pickup signal from other thus causing a crosstalk. STP -shielded twisted pair will eliminate crosstalk by shielding each twisted pair from other.

False. In terms of attenuation and data rate capacity it is better than UTP. It can transmit from zero hz to many millions of hz. It has low attenuation.Unbalanced signals doesn't affect these two characteristics of coaxial cable.
